Apartment House AVA, Andermatt
Special Housing, 2025
The fourth apartment house designed by OOS for Andermatt Swiss Alps AG, with its striking design, already convinced the competition jury in 2008. AVA impressively combines Swiss chalet architecture with the requirements of modern living.
The project was put out to tender as a timber construction with a high proportion of luxury apartments. It is to blend harmoniously into the dense built environment while meeting the highest standards of comfort and aesthetics. There are also plans for an exclusive spa area on the ground floor to cater to the demands of upmarket tourism.
The architectural vision developed is based on an intensive examination of the existing townscape. The combination of the chalet architectural style with functional interior design creates a contemporary Alpine living experience.
Design elements from the façade are repeated in the interior design. Generous room heights, fireplaces with traditional green tiles and well-thought-out furnishings offer residents an exceptionally pleasant living environment.
Abstract sgraffito patterns, used on the exterior, create a link between local tradition and modernity. The clear materiality of the timber construction runs consistently through the entire building.

House Uto, Zurich
Culture, 2025
OOS has been commissioned with the refurbishment of the historic ‘House Uto’. The aging housing stock will undergo a refurbishment and additional living space will be created by means of the roof extension.
Designed by Fritz Fischer in 1927, the building exhibits architectural features of Expressionism and Art Deco, which are rarely found in Zurich. In agreement and cooperation with the monument protection and the building owner, OOS has developed a refurbishment concept for the building. The building will be restored to its former glory and has already been listed as a historical monument during the planning process.
The reuse of the existing substance is part of the refurbishment concept. Much of it is preserved and will be reused after appropriate upgrading. Architectural features are preserved as far as possible, which at the same time contributes to a more sustainable project realization.

Energy, Logistics and Administration Building, Davos
Health, 2025
The energy supply on the Medicine Campus Davos is becoming sustainable. With the construction of the new energy, logistics and administration building, logistics areas and offices for the administration are being reorganised in addition to the new woodchip heating system. OOS is thus realising a further component of the master plan.
The Medicine Campus Davos is being restructured on the basis of the OOS masterplan. As part of this, the outdated and no longer legally compliant energy supply for current and future uses will be replaced by a wood chip heating system. At the same time, organisational optimisations and additional space are required. The new building solves these different requirements.
The demolition of the old building, which can no longer be used, will clean up the site structure. The designed replacement building blends into the surroundings and, together with the existing building, characterises the appearance of the site.
The forecourt of the extension with delivery areas and access roads is kept compact and enables daily deliveries throughout the year, especially during heavy snowfall.
The construction work is particularly complex and places special demands on logistics and safety. The new building is being constructed in an area that serves as a central distribution hub for heat and energy for the entire site. In order not to disrupt this supply, the distribution was moved to the strategically correct location before the demolition.

Research II Medicine Campus Davos, Davos
Office, 2024
As an international centre of competence, the Medicine Campus Davos combines research, therapy and education in one place. To expand research activities, particularly in the fields of allergy, asthma and cardiology, and to promote translational scientific approaches, a further building is being constructed: Research II.
The new building is located in the north-east of the Medicine Campus Davos. It is part of a comprehensive master plan that is gradually implementing the vision of an innovation location. The research activities will be expanded with the building and translational approaches will be given space.
Research II extends the existing building Research I with additional laboratory and office space and offers a modern research environment for the new future users. The architectural expression is based on the new buildings already realised as part of the master plan in order to emphasise the visual identity of the research location.
Inside, a striking cascading staircase forms the centrepiece of the building. The long access zone with several entrances to the rental areas opens up the possibility of setting up future sub-addresses.
An important feature of the interior design concept is a multifunctional body. This serves as a meeting zone and contains other important uses such as meeting and telephone niches. At the same time, it serves to spatially separate the various work areas such as the individual and group offices or the open space areas.
The building was tailored to the needs of the various user groups, including the CK-CARE, Cardio-CARE and Davos BioSciences research programmes already located on the site, with a fixed budget.

ORBIZ Josef, Zurich
Hospitality, 2024
At ORBIZ, the name says it all. Inspired by science fiction films from the 1970s, the new flex office has been created at Josefstrasse 214a in Zurich. The interior design concept designed by OOS does away with classic office structures and creates a prestigious working environment. This gives the ORBIZ brand a unique and individualised appearance.
The ORBIZ flex office commissioned by Pensimo is an example of the conversion of existing buildings. The new interior design is intended to strengthen the brand and give it a unique identity. An open and flowing spatial structure was Pensimo’s brief. The design is based on the look of science fiction films from the 70s.
A new entrance area, a café/restaurant and event and workshop rooms have been created on the ground floor. The catering area offers tenants and external guests catering throughout the day and will become a bar in the evening. the client’s aim was to promote interaction through the use of the ground floor and to open up the currently very introverted Josef office building. This was intended as a contribution to increasing urbanity and creating a quality of stay.
The flexible offices and meeting rooms are located on the two upper floors. These are formed in a circle like orbits, which are connected by flowing spaces in between. The available space ranges from individual workstations to larger work areas with a plug & play principle, which promotes the productivity and well-being of users through the indoor climate and acousti

Nest Margarethenstrasse, Basel
Office, 2024
As part of a repositioning project for the Nest Sammelstiftung, existing office space in the shell of the building was converted for initial letting. The office and commercial space is suitable for companies of different sizes, offers innovative forms of work and supports the community building.
In Basel, another project was realised for the ecologically ethical Nest Sammelstiftung pension fund: The extension of three floors in Margarethenstrasse. A total of 1,465 m2 of office space and 400 m2 of commercial space on the ground floor were created.
In order to make the space attractive, not only was the interior design developed, but the marketing strategy was also optimised in close cooperation with the client and Inspire 529. Prior to planning, it was defined who the future users would be and what their needs would be. The values of the new tenants and the use of the ground floor should be in line with the principles of the foundation.
The concept offers considerable advantages to future users. By dividing the office space into smaller units, a broader tenant structure is aimed for, with multi-year leases strengthening the sense of community. The creation of an additional community zone promotes collaboration and maximises space utilisation.
The building from the 1960s presented a structural challenge. With the exception of the office expansion, the building was completely refurbished and partially converted into flats. With the new interior design, a spacious and pleasant working environment was created, which cleverly exploits the ceiling height.

Apartment House Val Val, Andermatt
Special Housing, 2024
Val Val is already the third apartment building from the pen of OOS in Andermatt Reuss. Designed for Andermatt Swiss Alps AG, the new building impresses with its uniqueness and individual character. The result is exceptional and luxurious apartments that are specially tailored to the needs of families.
With the apartment house Val Val 15 apartments will be realized, including four penthouses. The architecture is characterized by the careful adaptation to the site, the environment, the use and the local climate.
The apartment building pays homage to the traditional Heimatstil, which draws on rural and regional architectural forms. This is complemented by modern elements and light-flooded rooms.
All apartments are generously proportioned. Large windows and loggias, which can be used as winter gardens, offer spectacular views of the mountains. The penthouses extend over two floors with high ceilings and a thoughtful duplex design.
Communal areas such as a lounge, a spa, two saunas, a cinema and a roof terrace enrich the spatial concept and encourage interaction among residents. Retail space is also located on the first floor.
The Val Val apartment house was developed in collaboration with blocher partners, who are responsible for the interior design.

Open Ride, Basel
Health, 2024
The opening of another Open Ride spinning studio brings a state-of-the-art fitness experience to Basel. With a unique interior design concept, the existing substance of the listed and newly renovated west wing of SBB Basel was brought to life in an impressive way by OOS.
Following the success of the Zurich branch on Europaallee, the second Open Ride was opened in Basel. The design concept from Zurich was translated to the location in Basel. This location in the listed SBB building, the former French railway station, offers a unique backdrop.
OOS helped with the search for a location, developed a study for the Basel railway station and supported the client in the application process. The interior design gives the studio a strong identity, embodies the values of Open Ride and serves as a flagship.
Clear spatial elements were created, including an eye-catching staircase and a specially designed box for a unique spinning experience. The interior design supports the customer experience from reception to the shower and optimises operational processes.
Particular challenges were the noise emissions, the building services under the listed roof and the coordination of the construction work in the busy railway station environment.

DDO Information Centre, Davos & Klosters
Retail, 2023
The Davos Destinations-Organisation was faced with a new challenge: in order to market Davos Klosters even more attractively, it needed a new, representative interior design. The redesign should strengthen the organisation’s identity and reflect the values of Davos Klosters.
The interior design project was dedicated to the redesign of the Davos Destinations-Organisation information centre in Davos and Klosters. The cooperative promotes Davos and the region as an attractive location for tourism. The aim was to give the brand a fresh, new look. The consistent use of the colours of the corporate design strengthens the identity. The use of wood brings additional warmth to the premises. Wherever possible, the same materials and elements were used for both locations.
Due to the limited budget, efficient planning and coordination was required. An interior design concept was developed, which was first realised in Davos and then in Klosters. The thorough examination of the existing building fabric at the beginning contributed significantly to the success. The new centre is inviting, functional and reflects the values of Davos Destinations-Organisation.

OOS Office Redesign
Office, 2023
When your own office becomes a testing ground for innovative design concepts and working methods: OOS has given its premises a new, surprising look.
In 2008, OOS moved into the brick building at Hardstrasse 245, where the interior fit-out was carried out to immediately create an inspiring working environment and emphasise the authentic character of the building. Shortly afterwards in 2009, Club Exil was opened on the ground floor, emphasising the lively atmosphere of the location.
15 years later, OOS decided to redesign the upper floor to reflect new forms of collaboration. A central element of the new design was the introduction of activity-based working. This flexible workspace model offers employees zones that can be used variably depending on their activities and needs.
On the upper floor, employees and visitors are welcomed by a generous, lush green area and a multifunctional room with communication zones. As part of the redesign, this area was equipped with a kitchen for drinking coffee, cooking and eating together, open meeting zones and individual workstations. The space serves as a dynamic place for spontaneous encounters, dialogue and work.
The individual group offices, each offering space for 4 to 8 individual workstations, are accessed from this central room. The offices are functionally designed and offer employees space for concentrated work as well as for team-internal communication. The following applies to these offices: Weekly Clean Desk Policy.
In line with a sustainable reuse approach, old office desks were converted into pedestals for plants and workstations, while former shelves now function as a library with an integrated meeting zone.

„Josef will wohnen“, Zurich
Culture, 2023
The „Josef will wohnen“ (Josef wants to live) initiative was launched as a counter-proposal to the development plans for the Josef site in Zurich and calls on the city of Zurich to rethink its project idea. Innovative approaches show alternatives for the site that focus on urban quality, mobility, density, preservation of buildings and the needs of residents.
The starting point for the „Josef will wohnen“ initiative is the Josef-Areal, a plot of land owned by the City of Zurich on which the former „KVA Josefstrasse“ waste incineration plant operated for decades. This is why the site is still located in the „zone for public buildings“. In recent years, the city of Zurich has developed a utilisation concept for an indoor swimming pool, flats for the elderly, a depot and other facilities as well as a small neighbourhood park.
In the meantime the rapidly developing centre around Hardbrücke has created a new situation: the Hardbrücke centre needs flats. And lots of them, for different sections of the population. This residential use has priority in such a central location in a rapidly growing city, alongside public uses such as an indoor swimming pool, healthcare facilities and flats for the elderly.
In particular, because the city of Zurich is coming a little closer to the one-third target for non-profit housing construction on its own land. The „Josef will wohnen“ working group, initiated by the Hamasil Foundation, has developed a new vision for the site based on the City of Zurich’s ideas. This will create 400 to 600 additional non-profit housing units and thus living space for around 1,000 people.
Three urban design variants were developed, including a perimeter block with a high point, a Brazilian-style composition of two high discs and a semi-circular courtyard and a playful stacking of residential buildings and terraces. Densification, open, green and neighbourhood spaces, climate-friendly construction while preserving the existing building fabric and short distances into the city are key considerations. The initiative calls on the city of Zurich to rethink its planning and examine these alternative approaches to urban development.
A special feature of the design is the use of parametric tools for urban development usage scenarios, which are automated and parameterised with the help of Grashopper and ArchiCAD. This enables the effective and efficient development of variants and thus the urban design of the Josef-Areal.

Residential Complex, Oberengstringen
Special Housing, 2023
In a study commission for the ecological-ethical pension fund Nest Sammelstiftung, which was created in collaboration with the project developer befair partners ag, a new residential complex should be built in Oberengstringen. The new building is expected to be of high ecological, economic and socio-cultural quality. OOS has developed a design based on the principle of maximum CO2 savings and thus narrowly misses out on the competition.
The architecture surprises in expression by approaching the locally predominant language of the building structures, which mainly date from the 1960s, and thus blends into the existing context in a restrained manner. The design envisages two buildings with a total of 21 residential units.
Each floor has its own individual character. The floor plans, which are easy to furnish, can be used in a variety of ways. The static timber construction system of columns and slabs with Timber Structures 3.0 technology is a novelty and offers maximum flexibility in room design, both today and for future conversions.
The construction consists mainly of natural and low-CO2 materials such as wood, straw, clay and sandstone. The window areas are designed for good natural interior lighting. Ventilation is manual via the windows. The orientation of the building and the degree of opening of the façade optimise solar gain. The minimum energy requirement for the building services is covered by a PV system on the roof, so that the building is CO2-neutral in operation.
The landscaping with gravel areas, rough pastures, trees and shrubs as well as local sandstone promotes biodiversity and avoids sealed surfaces as much as possible. It invites visitors to linger and play with a variety of activities. An underground gallery was not built in order to save grey energy and construction costs.

Extension Weingarten Retirement and Nursing Home, Olten
Health, 2023
An extension is planned for the Weingarten retirement and nursing home in Olten. The extension of the east wing is also intended to improve its earthquake resistance. OOS opted for wood in the competition and came in second place. The pioneering concept could significantly reduce CO2 emissions and create a healthy, natural living environment.
The municipality of Olten needs additional capacity in the Weingarten retirement and nursing home. The east wing from the 1970s is to be extended. The brief included a two-storey extension for a further 20 rooms for the residents and common areas as well as the earthquake-proofing of the existing building.
The vision of adding storeys and seismic retrofitting with as little grey energy as possible finds its solution in timber construction. Compared to concrete construction projects, up to 62% CO2-equivalent emissions could be saved. In addition, an efficient and short construction process would be possible, which would lead to less disruption for the residents during construction.
The façade structure was designed to harmonise with the main building. The appearance of the extension thus follows the structure of the existing building. Spacious communal areas offer residents attractive views. The interior design emphasises naturalness: visible wood, clay subfloor, clay walls. The project aims to combine ecology and well-being in a healthy and forward-looking living environment.

„Blühende Pfingstweide“, Zurich
Culture, 2023
Once a cow pasture at Whitsun, then an industrial quarter, then an up-and-coming trendy neighbourhood. Today, where a new Hardbrücke centre is supposed to flourish, boredom and monotony loom. The „Blühende Pfingstweide“ (Whitsun willow in bloom) working group is fighting against the disappearance of the industrial era and in favour of a lively, urban and attractive Zurich West.
The south-eastern part of the Welti-Furrer site is currently dominated by a multi-storey car park, a warehouse and a car park. To the north-west, the commercial and office building „Prime 2“ dominates the site next to an old office building. Despite the conflict with the special utilisation plan, the city of Zurich approved Knecht Holding’s plans for two further identical new buildings, „Prime 1“ and „Prime 3“, designed by the Max Dudler architectural firm.
A lot has changed since the adoption of special utilisation planning twenty years ago. The climate crisis requires the conservation of grey energy and the integration of existing buildings into future plans. The former motorway planning on Pfingstweidstrasse is obsolete, and Zurich West has become a central area with housing requirements.
The „Blühende Pfingstweide“ working group initiated by the Hamasil Foundation developed a vision with the aim of creating a lively, green living and working space on the Welti-Furrer site. Instead of more boring office blocks, existing structures are to be repurposed, supplemented with a residential tower block and integrated into a green urban landscape. The vertical design also serves to solve the noise problem along Pfingstweidstrasse.
The project objectives focus on integrating the area into the urban fabric, emphasising diversity, contrasts and interaction areas. The realisation requires a residential proportion of at least 30 percent, whereby the working group envisages targeted greening to avoid increased sealing.

Coca-Cola HBC Schweiz AG Headquarter, Opfikon
Office, 2023
The beverage company needs a new, attractive and future-oriented office for its Swiss headquarter. OOS accompanies the client in a new building near Glattpark and develops an interior design concept aligned with the company’s vision and culture. With strategic change management, OOS also helps creating a change in work culture.
The new headquarter serves as a collaboration space, with the premises extending over two floors. The diversity of the Coca-Cola HBC Schweiz AG brands represent an inspiring starting point for the design approach and are translated into a rich spatial configuration. Different spatial and working situations are used to create an office tailored to the various forms of collaboration and levels of confidentiality.
The overriding goal of office organization is short distances and unplanned encounters. This maximizes innovation and know-how transfer without specially designed processes. This is why the reception, all workstations and the cafeteria are together on the 3rd floor. Mixing of internal and external people should be deliberately avoided in the workplace areas. The organization and design of the new office environment follow the aspects of biophilic design and thus support the productivity, engagement and individual physical and psychological well-being of the employees.
An iterative development of the workstation zones results in a new desksharing ratio for an optimal organization of the office. As a result, from the original 100% allocated workstations, a 65% desksharing ratio is achieved. On approximately 3’100 m2 160 workplaces for about 245 employees are created. The spaces follow a clever arrangement that on the one hand promotes social interaction and team organization, and on the other hand takes into account confidentiality in the workplace. The flat hierarchy at Coca-Cola HBC Schweiz AG is also reflected in the workplaces – individual offices are consistently avoided.

KOWERK, Dietlikon
Office, 2023
OOS supported the owner AXA Anlagestiftung in the strategic repositioning of a property built in 1993 at Industriestrasse 24 in Dietlikon. With clever interventions on the level of architecture and interior design, the building was refurbished and adapted to the new needs.
Starting from a purely private individual office structure by a main tenant, the building was redesigned through various interventions. The result is the KOWERK office and commercial building. This project is characterized by a variety of possible uses with areas for offices, trade and services. Due to the new multi-tenant structure, the vision for the property follows the idea of “easy-in/easy-out”.
On the ground floor there are public areas for gastronomy, showrooms, retail space and two-storey manufactories, which are connected to the first floor. The heart of the building is the atrium.
On the upper floors, the offer ranges from approx. 10 m² of small micro offices for start-ups to approx. 6’621 m² for established companies. A collab space on the 6th floor and storage rooms in the basement round off the space offer.
Due to the continuous maintenance of the building since its construction, the building fabric was basically in good condition. This had resulted in the requirement to revitalise and refurbish the existing building with as little intervention as possible. Obstacles that come to light during the conversion were responded to in an agile manner and structural decisions were adapted during the process.

Apartment House Koya, Andermatt
Special Housing, 2022
Another apartment house from the pen of OOS has been built in Andermatt. The construction of Koya for Andermatt Swiss Alps AG is the second proof that comfort and design do not contradict each other even in the smallest of spaces. In addition to the use of wood for the façade and the interior fittings, the small space requirement characteristic of micro living also ensures a reduced ecological footprint.
The Koya apartment house stands for practical yet stylish living space, where architecture and interior design complement each other. Within the existing minimal space conditions, the aim was to achieve the greatest possible effect.
The concept of Koya is based on the idea of connection: Wood is an expression of closeness to nature. Architecture and furnishings merge into one another. Further special features result from the analogy to Japanese culture.
On the other floors 1 to 3, nine mezzanine flats are arranged, each with a ceiling height of almost five metres and one or two bedrooms. The mezzanines offer maximum space and versatility with their built-in furniture.
On the top floor are three penthouses with twice as much space. Generous window fronts dissolve the boundary between inside and outside.
Other communal spaces on the ground floor, such as the lounge with fireplace or the sauna with garden, create connecting places between public and private spaces and thus encounters among the residents.

Expansion Wüest Partner Office, Zurich
Office, 2022
In a study commission for the expansion of the existing office landscape by Wüest Partner, OOS emerges as the winner. With the idea of “The Garage”, the existing concept of the Knowledge Exchange is expanded with additional usable space and connected to the existing rooms.
Back in 2013, after winning the study contract, OOS was commissioned to design the office landscape by Wüest Partner in the Alte Börse in Zurich and the Knowledge Exchange was created. This central idea was further developed with the idea of “The Garage”. “The Garage” is a reference to the garage as a starting and development location for success stories of well-known companies. It stands for Wüest Partner’s culture of innovation and performance and underlines its positioning.
The expansion adjoins the existing premises on the 3rd floor and is connected to the 4th floor with an additional staircase. One challenge was the optimal use of the space formerly rented by a public school. The newly created office workplaces as well as informal meeting zones enable activity-based working and follow the 4C principle: Concentration, Communication, Collaboration, Contemplation.
Other important aspects were ergonomics, acoustics and room climate to promote the well-being of the employees, as well as the expansion of the meeting rooms. These have a variety of digital equipment and promote interdisciplinary collaboration with more flexibility.

Apartment House Frame, Andermatt
Special Housing, 2022
In Andermatt, OOS redefines modern alpine living with the design of the Frame apartment house. The clever and eye-catching building with innovative micro-apartments sets new standards for small living space with a high quality of stay.
Andermatt already has many spacious apartments in the luxury segment. The apartments of the Frame apartment house meet the needs of a young, active clientele. Through the densification and the resulting space efficiency, microapartments have been developed, which offer a high quality of stay and at the same time leave a smaller ecological footprint.
The outer shell is not a masonry structure but a wooden façade. Five uniformly designed exterior elevations and the defining roof with its cantilevers merge into a single entity. Interior and exterior spaces. Interior and exterior spaces are connected by bay windows that complement the main facades. The panoramic windows allow expansive views. With their beveled reveals, they refer to the window openings often seen in alpine houses. The windows thus provide light-flooded interiors.
The 34 apartments are a mix of vertically arranged high duplex and maisonette apartments, horizontally arranged 2.5-room apartments and three studios. A multifunctional volume, at the same time bathroom, kitchen, bedroom and built-in closet, characterizes the 2.5-room and the maisonette apartments. Architecture, interior design and furnishing form a unity and shape a unique spatial and living experience. A room height of around 5 meters gives the maisonette apartment a stately feeling of space despite a comparatively small floor plan of just about 40 square meters.
While the apartments are tailored to the needs of the ownership, the first floor comes up with additional spaces. A community room, a community kitchen, a fireplace room, a sauna with garden and an additional community garden can be used equally by the entire resident community.

HGK Therapy and Gastronomy, Davos
Health, 2022
The Hochgebirgsklinik Davos, as part of an ambitious master plan for the Medicine Campus Davos, is seeking to reposition itself with a focus on hospitality. The new building for gastronomy and therapy is intended to strengthen the rehabilitation experience, improve the quality of stay and use in favour of health promotion and support the positioning of the clinic.
The gastronomy and therapy wing adjoins the existing main building to the south. This creates a new appearance and a new reception situation. The newly designed foyer moves into the centre and connects the lobby with the campus floor. It thus becomes the focal point in the building and mediates between the public and semi-public areas. This simple spatial organisation optimises orientation as well as the flow of movement and daily routine of the users.
The therapy area with treatment, training and wellness rooms is organised around the two-storey gymnasium and ends with the therapy garden outside.
Analogously, the gastronomy area is organised around the central kitchen, thus creating short distances. The different restaurant areas cover the needs of the private, semi-private and general insured as well as families.
The building volumetry is deliberately kept low so that the attractive view of Lake Davos and the surrounding nature from the rooms is still guaranteed. In addition, most of the programmes that determine the patients’ daily routine are located on one floor. Due to the column plate structure, the construction follows the logic of a changeable building.
The striking white aluminium grid integrates the new building into the complex and creates a structural sunshade that guarantees an unobstructed view. Natural materials, bright and clear rooms, differentiated light and colour moods create an inviting, unobtrusive and health-promoting hospitality atmosphere.

Swiss Pavilion EXPO 2020, Dubai UAE
Culture, 2021
The team led by OOS won the EDAs planning competition for the Swiss Pavilion at EXPO 2020 Dubai UAE. The concept “Reflections” invites the world to experience Switzerland while traveling and to get to know surprising facets of the country. With «Reflections» the team presents an innovative implementation of the given core messages in space and experience. The body of the building combines tradition and innovation, sketches relationships between Orient and Occident and creates a unique presence.
In terms of content and dramaturgy, «Reflections» is reflected in three acts in which the audience experiences selected facets of Switzerland. In the first act, the audience is already invited in the queue to help shape the facet «typically Swiss» – interactively through the reflection in the mirror.
The journey continues into the interior of the pavilion for the second act. Here the facet «unique experience of nature» is staged. The audience strives towards the dramaturgical climax: they walk uphill through real fog. The moment they emerge from the fog, the surprising view of a mountain panorama is revealed.
After traditional and nature-oriented Switzerland, the third act covers the facet «urban and innovative environment». Here Switzerland presents itself both as a workshop and as a showroom for innovations.
In addition to these three acts, other areas were designed such as a rooftop terrace overlooking the Expo’s Opportunity District where the pavilion is located, a VIP room and an event space.
One of the major challenges in architecture is the expected high density of people as well as the diverse needs and expectations of international guests. OOS meets these challenges with user-oriented, innovative design. The architecture adapts to the geographical and cultural diversity of the visitors on the levels of function and emotion with intuitive communication and spatial orientation.

Monaco Pavilion Expo 2020, Dubai UAE
Culture, 2021
The architecture designed by OOS convinced in the competition. Together with facts and fiction GmbH and NUSSLI, OOS was awarded the contract for the Monaco Pavilion at Expo 2020 Dubai.
The development of the design for the polygonal crystal shape was based on the leitmotif „Strong, small and beautiful“. With this iconographic appearance, the pavilion invites the world to explore the country. With strong symbolic power, the Monaco Pavilion asserts itself in the international environment of Expo 2020. The crystal with diamond-shaped facets on a rocky background embodies the versatility and strengths of Monaco – its internal cohesion as a nation as well as its strong partnerships and connections with the world – key elements of Monegasque policy and a fitting expression of the Expo Motto “connecting minds, creating the future”.
The architecture of the pavilion surprises with a polygonal and faceted structure and constantly changing perspectives. The rocky base is also an homage to the „Rocher de Monaco“ and stands as a symbol for tradition and future of the principality. The strengths of the small state are also given a large stage on the content level.
The exhibition section is divided into two scenographic areas. In the „Garden of Opportunities“, visitors engage with Monaco‘s excellent and future-oriented projects. In the „Identity Show“, Monaco‘s history, culture and values are conveyed in a spectacular 360-degree multimedia installation.
The entire construction follows the principle of simplicity and sustainability: The crystal, for example, consists of solar panels visible from afar, which are mounted as a shell in front of the simple body of the building and merge into a light, playful and highly aesthetic overall image.

Administration Building with Bus Parking Hall Appenzeller Bahnen, Herisau
Industry, 2020
An Appenzellerhaus as a bus shelter and administration building: OOS AG’s competition entry complements the development area at Herisau railway station with a simple and clear longitudinal building. Anchored in the local urban and architectural building culture, it combines tradition with future-orientated, climate-friendly construction.
The existing bus depot in Herisau has become too small and is to be replaced. Based on the development concept, the aim is to achieve urban densification. For this reason, Regiobus AG and Appenzeller Bahnen AG have decided to jointly construct an administration building with a bus depot on the ground floor.
The new building developed as part of the competition is a simple functional building, which nevertheless remains representative in its expression. The different longitudinal and transverse façades, the pitched roof and the colour scheme are analogous to the classic Appenzell houses. The bus garage and administration building are architecturally recognisable. The continuous window grid offers maximum flexibility for the division of the office space from single, double and quadruple to group offices and open space organisations.
The building structure and the building services concept are designed to minimise CO2 consumption during construction and operation. To this end, a lightweight timber construction is planned for the office floors above the concrete structure on the ground floor. The reduced width of the building means that all areas are optimally exposed to natural light. At the same time, ‘natural ventilation’ of the office areas is possible. The building services are adjusted for optimum comfort using building simulation. The green roof areas support the microclimate by counteracting the heat island effect and naturally supporting biodiversity.

PartnerRe Office, Zurich
Office, 2020
OOS accompanies PartnerRe in its overarching strategy for sharpened differentiation. The developed interior architecture is an expression of the entrepreneurial vision and values of the reinsurer. At the location in Zurich West, office environments of around 5500m2 have been created, which bring collaboration and communication to the center.
After a successful competition phase, OOS is supporting the internationally operating reinsurer PartnerRe with the development and implementation of the new vision for its office environment at the Zurich location. The move from the previous office building in the exclusive Seefeld area to the urban „Zurich West“ is part of the company‘s overall strategy to strengthen its differentiation. With the design of the „single-tenant“ tenant fit-out in the new Allreal office building, OOS is pursuing PartnerRe’s strategy in a pioneering way on an area of 5500m2.
The new premises promote a collegial, family-like working culture and underline the reinsurer‘s collaborative and partnership-based principle. The spatial result is preceded by the demanding process of bringing together the different aspects of the company‘s values with the aim of setting PartnerRe apart from other reinsurers, also in terms of spatial appearance. This led to the interior design requirement to express values such as trust and reliability and to combine these with openness, agility and a touch of youthfulness.
Collaboration and communication are not only central as corporate values, but also in the premises: attractive, cleverly placed communication areas and internal staircases structure the rooms and thus support a collegial work culture. The concept of „Verdichtung“ visually differentiates the different room areas and at the same time creates an arch across the entire building. From visually quiet room areas to densely populated „centres“, the wide range of rooms is placed in a context where visitors and employees can orientate and move intuitively.

Sonova Communications AG Headquarter, Murten
Office, 2020
A groundbreaking new building has been constructed in Murten: one of the first CO2-neutral office buildings in Switzerland. The competence centre is an expression of the innovative strength of Sonova Communications AG and offers a contemporary working environment with the highest quality of use. The architecture thus creates differentiation and identification.
Sonova Communications AG is active in the development and construction of ultra-miniaturised wireless technologies. The innovative new building offers a unique indoor climate for around 150 employees and is part of the technology and market leader’s sustainability programme.
On the urban planning level, the slightly concave building structure is oriented along the moraine of the terrain. It opens up towards Lake Murten and creates an inviting gesture for employees and visitors. The spatial organisation intuitively follows the operational processes. Thus, the entire research and development department is arranged on a single upper floor with an area of around 2000m2. The ground floor houses the test rooms for high-tech communication technology, the logistics department, the reception with adjoining showroom and an inviting bistro and coffee area.
In the building envelope, the architecture focuses not only on the quality of the interior and the workplace, but also on energy efficiency. The architecture allows for an almost energy-autonomous building. The envelope is kept compact and the proportion of windows is optimised. With high interior spaces, high-ceilinged windows and skylights, natural daylight is channelled deep into the rooms.
In interaction with windows, solar radiation and waste heat, the temperature- and humidity-balancing surfaces and materials create a pleasant indoor climate without active heating or cooling. The use of solar energy and waste heat from people, machines and computers is used to heat the building.
In addition, the building is powered 100% by PV electricity. With this overall passive, clever space and construction system and the absolutely minimal use of building services, the building is a CO2-neutral office building in operation.

Swissbau Innovation Lab 2020, Basel
Culture, 2020
OOS has created a unique architectural concept for the Innovation Lab at Swissbau 2020. It is based on the vision of a “city of digital transformation” and stands for an extraordinary, reciprocal relationship between content and staging.
The Swissbau Innovation Lab is the special show for digital transformation within the framework of the Swissbau exhibition event. The aim of the special show is to demonstrate the new technologies in the construction and real estate industry and to make them tangible with possible applications.
The architecture was required to provide a timeless framework for the content and at the same time to transport it itself. OOS’ approach: In the sense of differentiation from the usual image of densely packed exhibition stands, the architectural concept of a city was developed for the special show. Despite the high density of stands, it is characterised by empty space, width and a great clarity.
The area was divided along the contents: An “Innovation Village”, a “Networking Zone”, a “Speakers Corner” and the highlight of the special show and central element of the architectural staging, the “iRoom”. It is a state-of-the-art experience space for digital planning. Here, the innovation projects were staged as a 3D cinema in an interactive show. A real atmospheric contrast was created by a bistro designed as a green oasis with real plants.
At the centre is the town square, which with its atmosphere of generosity serves as a haven of peace and is thus a counterpoint to the lively trade fair business. The stands – so-called Innovation Points – are arranged around the square in quarters, streets, squares or avenues. Based on the architectural concept of a city, OOS developed an innovative orientation aid with a theme-related naming of streets, alleys etc.

Akzess, Horgen Oberdorf
Office, 2019
With the project AKZESS, OOS is setting the course for future uses at the former Schweiter industrial site in Horgen Oberdorf. The name says it all. The project, which was submitted as part of a study, lends the area in a prominent location directly at the railway station a unique urban identity that is characterised by openness and accessibility.
This project goes beyond the requirements of a market-driven offer for living and working including supplementary services – AKZESS stands for living spaces for the future. By this OOS means a green urban interior surrounded by a hard architectural exterior – the two buildings “HILLSIDE” and “LAKESIDE”. The two new buildings create an interesting relationship to the existing substance. The staggering of the buildings in a transverse direction to the slope optimises the view for the apartments in the old and new buildings.
In the sense of permeability and accessibility, different uses, apartment types, open spaces, squares and passages provide the desired individual atmospheres. AKZESS also stands for great flexibility in terms of structural adjustments for possible future uses. Thanks to its modular structure, apartments can be converted into office or commercial space and vice versa.

Open Ride, Zurich
Health, 2019
Open Ride opens its first studio in Zurich. OOS has translated the concept of “the future of fitness” for the new indoor fitness brand. The result is an environment for a unique workout experience that involves all the senses.
The challenge of getting the maximum use out of a small space while still creating an atmosphere of spaciousness – this was achieved by OOS with a well attuned and high-quality colour, lighting and material concept. The existing premise was equipped with a reception desk, a coffee/tea kitchen as well as cloakrooms and toilets, all within a short construction period and on schedule. The custom-made furniture is user-oriented and at the same time adapts ideally to the space conditions.
The heart of Open Ride is the prefabricated “box”, which combines club and training feeling at the same time. Assembled on site, it offers strong sound absorption and is equipped with sound-insulated ventilation pipes. Inside, a total of 300 metres of LED pixel strip provide an incomparable light show. Together with the indoor bikes and the sound system, the desired atmosphere is created, in which training, party and concert merge into an experience involving all the senses.

Data Center ETH Hönggerberg, Zurich
Education, 2019
More than “zeros” and “ones” – in the design for the new data centre at ETH Hönggerberg, OOS takes a step beyond the obvious. The design for the five-storey new building combines the demand for maximum benefit and the option of possible future developments with a unique shell.
The facade design follows the principle “form follows content” and is produced directly from the computer using the “design to production” process. Thus, partially punched surfaces draw “zeros” and “ones” on the facade. The dynamic conundrum poetically reflects the context and contrasts with the speed of the computer operations inside the building. Through the choice of material – chrome nickel steel – the façade skin reflects and thus helps the compact volume of the new building to a dematerialized lightness.
The unique façade design also ensures that the new building stands out visually from the existing structure. In terms of urban planning, it blends in harmoniously with the existing building and leaves room for future expansion. Inside the building, the organization features simple, clear room sequences. The materialization – raw, bright and real materials – creates an analog contrast to the digital world.

Fischer Immobilienmanagement, Zurich
Office, 2019
The company Fischer AG Immobilienmanagement stands for unconventional and sustainable real estate projects. OOS translated this into the new company headquarters: In the old silk dye works on Lessingstrasse in Zurich, an office space spanning several floors was created with an extraordinary atmosphere.
The old building structure, previously refurbished by OOS, offered a unique starting point: a large hall with columns, exposed sandstone retaining wall, shed roof and view of the Sihl River. In addition, a long, narrow upper floor, without internal connection. Together with the client, OOS developed the vision of a two-story open-plan office with a surprise effect. The claim: It takes into account the needs of the various organizational units and makes Fischer AG Immobilienmanagement’s unconventional approach to projects tangible – spatially, atmospherically and materially.
The result: a narrow internal steel staircase spatially binds the two floors together and enables the organizational separation between concentrated work in the hall and public uses on the upper floor. Acoustic panels, which are completely integrated into the structure of the Sched roof, provided an optimal solution to the challenging spatial acoustics in the hall’s open space.
The actual heart of the design lies in the small office forest at the entrance. Anyone entering is surprised to find themselves in front of a green wall. A large variety of plants and overwhelmingly tall fir trees in huge steel troughs break the view into the space. The reception area also surprises – with its orientation into the space. The company’s values were translated into a unique spatial experience that, thanks to plants and natural surfaces, is also perceived as a healthy as well as stimulating work environment.

ZPA Lessingstrasse, Zurich
Hospitality, 2019
OOS has transformed the old building structure Lessingstrasse 11-17 with different levels of structural intervention into a progressive location. The independent project captivates by its characteristic spatial structures. OOS has combined this diversity with strategic planning and targeted renovation to create a new unit.
An old building fabric with varying levels, small-scale floor subdivisions, diverse spatial structures and building systems – the initial situation of this project was highly complex. But this is precisely where the great potential of the property lies. With targeted and unpretentious interventions, OOS succeeded in transforming the old building structure into an independent, progressive location while at the same time preserving a piece of history for the city of Zurich.
In a feasibility study, OOS worked with the owner to define the visions, target groups and future uses and determined the depth of intervention. The aim of the planned refurbishment and upgrading was to preserve the unique effect of the building structure for future generations.
Accordingly, interventions were only made where they were necessary for earthquake and fire protection. While the roofs were renovated for energy efficiency, the façades were only insulated on the inside in the area of the window parapets. Externally, the appearance has only been changed by demolitions to clean up the structure.
Inside, the stairwells have been freed from fixtures and, with the new lighting concept, contribute to the strong appearance of the property. Where possible, the different surfaces and structures have been left as they are, and subtle interventions have been used to bind them together into an atmospherically coherent unit. In addition to the staircases, the exposed sandstone retaining wall is a unique element that will have a strong influence on future tenant improvements.

MoneyPark Headquarter, Zurich
Office, 2018
The financial consulting firm MoneyPark AG in Zurich once again relies on the adaptable and sustainable design concept of OOS. The customer zones and the headquarters were brought together both in the locality and on the design level.
In just four months from the start of the project, the entire area was shaped and defined organisationally and atmospherically with just a few elements: A central area with meeting rooms and a café corner for meetings and stays was created in the headquarters.
The workplaces were designed to be very flexible and compressible with the use of benches. OOS has thus made the appearance of the headquarters “experienceable” and “perceptible” according to the design concept. Thanks to early and consistent coordination with the client, the short planning and construction time and the high coordination effort with the basic construction could also be successfully mastered.

HGK Extension and Renovation of the Main Building
Health, 2017
The renovation and extension of the existing main building of the Hochgebirgsklinik Davos has strengthened the rehabilitation experience and improved the quality of stay and use. This supports the repositioning of the clinic with a focus on hospitality. At the same time, the alpine clinic is an important part of the ambitious master plan for the entire Medicine Campus Davos.
The main building with the bed wing underwent floor-by-floor interior renovations while the clinic remained in operation. The existing building was made ready for the next generations by adding an additional 17 rooms and an earthquake retrofit.
The new, more spacious room types of the extension fit into the concept of “first-class rehab hospitality”, while the lower floors were developed to a lower standard. Private, semi-private and general rooms thus cover the needs and demands of the target groups of the Hochgebirgsklinik Davos.
A warm hospitality atmosphere was created through the use of natural materials, bright and clearly arranged rooms, differentiated lighting and colour moods, and an inviting yet non-intrusive atmosphere.
Architecturally, the extension is based on the existing expression of the building, without continuing to build on the existing structure one-to-one. The enlargement of the room grids of the extension creates an exciting addition to the façade, which underlines the new appearance of the clinic.

Research I Medicine Campus Davos, Davos
Education, 2019
With the new building Research I, an international centre of excellence for research, treatment and education in the allergy field is being created. The new building meets the complex requirements arising from its use as an educational campus, research laboratory and office.
The institutions SIAF, CK-CARE and Hochgebirgsklinik Davos are pooling their expertise: In Research I, which is directly connected to the Hochgebirgsklinik Davos, the spatial proximity of the three partners creates synergies and unique added value for researchers, medical staff and people with allergies or asthma. The new building was the first step in an ambitious master plan for the entire area of the Medicine Campus Davos.
Both the architecture and the interior design of Research I meet the complex requirements resulting from its multiple use as a training campus and research laboratory with offices under one roof. Various training rooms, a congress hall and a foyer are located on the ground floor. Office and laboratory workplaces on the upper floors round off the range of uses. The technical challenges of the building and the requirements for the laboratory areas (BSL 2 and BSL 3), coupled with a tight budget, proved to be particularly demanding.
The metal grid on the exterior façade fulfils several functions. On the one hand, the public ground floor is distinguished. On the other hand, the different façade grids for office and laboratory use are covered and tied together. The grid also serves to regulate the solar gain and to clean and maintain the façade, which is thus made possible despite the fixed glazing of the laboratory windows while the building is in operation.

Nest Commercial Building, Regensdorf
Office, 2017
A commercial building in the industrial area of Regensdorf – in this study OOS goes beyond function and aesthetics. Like a cloth, the photovoltaic system in the Minergie A-Eco standard covers the building and gives it an unmistakable expression.
With its design, OOS meets the demand for flexible use of the building. Due to the location and design of the core, rental spaces can be divided into four almost identical zones. The through-flow of the development is an architectural element and at the same time it organises the different uses efficiently and clearly with short access routes. The doubling of the building structure on the first floor not only achieves the desired division of usable space – the separation of the two “office blocks” by a single-storey inner courtyard creates a spatial quality of stay and is an unmistakable architectural feature.

Allreal Baufeld D, Zurich
Office, 2017
Allreal is planning its new headquarters at a prominent location in Zurich West. OOS’ response to the study is a concise and differentiated project that creates references to the surrounding urban spaces on all levels.
Externally, the building attracts attention with a subtle conciseness. The eye-catching features are the end facades turned out into the street space and a first floor clad in a glass skin. These underline the public character of the building and anchor Allreal to the maximum in the street space. Behind the glass skin is a foyer, which is complemented by a showroom and an auditorium.
From the first floor, dark steel frames and clinker infills visually tie the office floors together – a reminiscence of the architectural history of the site. Here, OOS has solved the requirements for different work areas with an elongated core: this filters the different zones into areas for individual workplaces and those for meetings and communal communication. The crowning glory is the top floor: in the meeting rooms, users are offered a view over the rooftops of Zurich.

LIIP reloaded, Zurich
Office, 2017
Enhancing the atmosphere of the office and making the organisation visible and tangible – OOS has redesigned the Zurich office premises of LIIP with innovative concepts and designs.
Even with the new lighting concept, the quality of stay in the open-plan offices could be significantly increased – a core concern of LIIP, an agency for digital products. In addition, the structuring of the space has created a surprising liveliness. OOS has translated central LIIP corporate values into design and developed the innovative concept of the “living shelf” together with LIIP.
This does not simply structure the space: The extremely versatile frame is – depending on the requirements – sometimes a separating element, seating and communication platform, sometimes a meeting zone, storage space or place of retreat. It runs through all four floors as a visual orientation aid and identity-forming element.

Raiffeisen, Zofingen
Office, 2016
One bank, three locations and the topic “Stubenbank” – OOS has supplemented the specifications of the Raiffeisen Region Zofingen with a core statement, derived values from them and translated them into a spatial concept.
Based on an analysis of the basic attitude and vision of the Raiffeisen Group – and specifically of Raiffeisen Region Zofingen – OOS has expanded the idea of the “Stubenbank”: In the concept “Guest at Raiffeisen Region Zofingen”, bank customers become guests. Accordingly, this positioning is reflected in the form of diverse qualities of stay in the spaces. Public, mixed and private zones are created.
The organisation of the rooms serves to guide customers. It creates insight and overview where desired and privacy and discretion where necessary. The elements and spatial structures are identical in all three branches and are adapted to the respective location. The zones of the customer areas are given an overarching colour and material concept, which is differentiated to distinguish the respective use.

Bruker Headquarter, Fällanden
Office, 2016
Cutting-edge technology indoors and out. Bruker, one of the world’s leading metrology companies, has commissioned OOS to build a prestigious company headquarters.
OOS had one and a half years to complete the technically demanding building ready for occupancy. The façade and interiors were to radiate the company’s innovative strength and quality standards and have a representative effect.
A precisely drawn profile in anodised aluminium was chosen for the façade. The vertical alignment of the pilaster strips supports the representative appearance of the building without making it look cumbersome.

Moods Refresh, Zurich
Culture, 2016
With a modified colour and lighting concept and a new bar, OOS is helping the Moods jazz club to a new splendour in just eight weeks of construction time. The club has also upgraded backstage, both technically and organisationally.
The new material and colour concept moves away from blue towards warm red tones, woods and brass. Accordingly, the revised lighting concept supports the desired warm atmosphere. The ambience is created not only by the lighting but also by the new bar, a dynamic body.
Seating steps have been installed on the gallery and the railing has been replaced by a black lattice. In the interests of user-friendliness, a staircase now leads directly to the artists’ dressing rooms.
The construction of the new offices proved to be particularly challenging. Spatially, they are located above the existing box and below the ceiling of the shipbuilding building. Thanks to a bridge construction, the roof of the box is not loaded – the load is distributed over the walls of the box.

EXPO 2027, East Switzerland
Culture, 2015
“La Suisse Orientale” – with the competition entry for the national exhibition EXPO 2027, OOS presents a new view of Eastern Switzerland. The three main locations of Sittertobel, Lake Constance and Schwägalp will be staged in terms of content and geography.
At the centre of the concept are the three main locations, whose geographical, social, economic and cultural characteristics define the three core themes: “permanence”, “changeability” and “permeability”. The main locations will be linked in terms of content and transport by a network of thematic routes, so-called “passages”. Existing infrastructures will be expanded and temporary ones can be used beyond the EXPO. This takes the aspect of sustainability into account.

Master Plan Medicine Campus Davos, Davos
Education, 2015
The Medicine Campus Davos aimed to realign itself into a progressive campus with clinic, research and education. With a master plan, OOS has created the basis for the future urban disposition of the clinic area and is implementing the vision step by step.
In terms of urban planning, the conglomeration of buildings that has grown over the past 120 years was restructured to meet the requirements. On the one hand, the master plan brings together the different usage requirements of various partners and thus supports the development of the entire site. This creates optimal functional and operational conditions for the various uses of the clinic, research and education, and maximizes the view of the valley and Lake Davos for existing and future uses.
The newly created continuous campus floor serves as an architectural organisational principle. As a connecting element, it brings together the various existing and new uses. These are all accessed via it. This optimizes orientation and the flow of people. The master plan also allows for free play and further development in the western campus area. The potential of the area can thus be increased and fully exploited by future developments.

Phonak Extension, Stäfa
Office, 2014
OOS won the study contract for the south and west extension of Phonak with two different buildings. These are each related in expression to the neighbouring buildings. While the West building forms a medium-term development potential, the South extension is in planning.
The architecture of the new buildings, the qualities of the newly created outdoor spaces and the integration into the existing substance are designed for the needs of Sonova’s employees and future customers. The new buildings fit pragmatically and at the same time precisely into the existing context. While the southern extension makes a striking, simple statement and, in interaction with the existing building, creates an exciting outdoor space, the western extension complements the campus logically and naturally, both externally and internally.
The working environment facilitates solution-oriented forms of collaboration for the staff. In both buildings, an inner zone with meeting rooms and adjoining rooms divides the office zones and, despite the open-plan typology, generates more intimate zones that ensure peace and concentration.

Dentalclub, Steinhausen
Health, 2013
The Dentalclub is growing. OOS adapts the design concept for the second location in Steinhausen. The Dentalclub Steinhausen also makes a visit to the dentist an experience for patients – an experience beyond the usual visit to the dentist.
By creating specific spatial worlds for each activity and a portion of entertainment, the club is created that focuses on the user’s experience. The scenography creates an atmospheric density, with the contrasting spatial concepts composed into a coherent sequence.
The “Dentalizer” as the central zone connecting all the rooms has a white reflective atmosphere and functions as a neutralising space of movement around which the various programmes and activities are arranged. The patient is welcomed here and moves on to the waiting area, which is decorated in warm tones. In the treatment rooms, the space is divided into two areas by introducing a visual horizon. While the lower part is assigned to the sterile, white working world of the dentist, the ceiling – which is the focus of the patient – acts as an atmospheric view into the crowns of a forest clearing.

Stoffel Area, Mels
Hospitality, 2013
An innovative and attractive residential location is to be created on the 35,460m2 site of the former Stoffel old textile factory. The site is located above the town of Mels and comprises several factory buildings worthy of protection, which are to be converted and supplemented with new buildings. As part of the study contract, OOS has developed a diverse range of services for a heterogeneous population with different needs.
Context-specific residential forms with individual building types, façades and private and public outdoor spaces were developed for each building site. This diversity of offerings creates a diverse and lively neighbourhood with spaces for communal liveliness as well as individual retreat. A clear ensemble effect towards the outside is achieved through the analogy of the longitudinally oriented building types. At the same time, the differentiation of the new buildings in terms of mass, height and type reinforces the importance of the valley façade of the spinning mill and distinguishes the individual buildings from one another.
The relevance of the two factory buildings as contemporary witnesses is also taken into account in the interior of the quarter: the central courtyard as the heart of the area forms a lively centre. The semi-public and public uses such as the bistro, day nursery and fitness rooms activate the spaces at the back of the area and enliven the courtyard. A structure of demarcation and openness is created, in which the co-existence and cross-fertilisation of communal and private uses creates interaction spaces for residents and visitors.

Geberit Informations Center, Pfullendorf DE
Culture, 2013
The sanitary manufacturer Geberit is planning a new customer training and information center on the plant site in Pfullendorf (DE). With the aim of combining “technology with emotions”, OOS has developed an architectural concept within the scope of this study contract, which enables the Geberit brand to be experienced in all its facets.
The precise siting of the new building achieves both optimal visibility to the public and a direct spatial connection to the existing factory site. The emblematic building forms the welcome gesture for visitors and local residents. The shimmering white box only becomes a sign through its elevated position on the former embankment. In keeping with the architectural design, the structural concept follows a clear formal language.
The entire interior is characterised by transparency and the use of genuine products and materials. The staircase – the LINK – creates the connection between the box with the basis and the technology with emotions and functions as a central orientation element. It leads past the various product ranges and thus connects the technical aspects with the emotional experience.

Flumserei, Flums
Culture, 2013
Under the “Flumserei” brand, the 10,000 m2 site of the former Spoerry spinning mill will be subdivided into various product worlds and will be adapted to the new needs of offices, services and industry by means of structural interventions.
The Innobas area has the potential to become a work and meeting center for Flums and the region because of its large usable spaces. OOS was asked to lead an interdisciplinary team and develop a redevelopment concept for the campus of the former spinning mill. Under the Flumserei brand, the large factory building will be reawakened to new life and made ready for new users and their needs using an intelligent space concept.
The commercial and office facilities will be functionally equipped and based on a flexible space plan. The public rooms offer gathering space for the clubs and local residents of Flums. With the Flumserei, the entire Sarganserland-Werdenberg region will be strengthened. OOS previously completed test planning for the former owner, Spoerry AG, and guided the redefinition of its use from the very beginning.

Wüest Partner Office, Zurich
Office, 2013
In a two-part process, OOS won a study competition for the new offices of Wüest Partner against seven competitors with its concept “knowledge exchange”.
In the historic offices of the old stock exchange on Paradeplatz, where shares were once traded and then drinks passed across the bar, a new tailored work environment for one of Switzerland’s leading real estate consulting firms is being created. The new office setting offers a flexible layout with up to 150 workplaces in contemporary surroundings.
The main usage areas make possible specific work operations and promote communications flow and knowledge transfer within the company besides providing elegant customer zones. The spaces are divided into three ring-shaped zones (“develop”, “gather and distribute” and “exchange”). Along the outside façade ring, concentrated work takes place in spacious offices.
All permanent workplaces have ideal conditions for work. In the middle, three-part layer, one can withdraw or work in smaller groups. The central, two-story hall with a glass roof is the heart of the office environment and invites workers to linger and exchange ideas with colleagues.

Dentalclub, Lucerne
Health, 2013
In the middle of the Old Town of Lucerne OOS designed and realized the spatial concept for an unconventional dental practice. The specified aim of this dentist was to offer his patients an experience and make their stay in the Dental Club as varied and pleasant as possible.
By creating specific spatial worlds for each activity and a portion of entertainment, a distinctive dental club was created instead of a conventional dental practice. By means of the various spatial scenographies, an atmospheric density is created, with these contrasting spatial concepts being composed into a coherent sequence. The design concept makes use of classical elements for this purpose and supplements them with surprising details.
Accordingly, the patient is welcomed into the warm and inviting atmosphere of the “fireplace room”, where he can pass the time and distract himself with an iPad and books. The “Dentalizer” as the central zone connecting all the rooms has a white, reflective atmosphere and functions as a neutralising space in the middle around which the various rooms and activities are arranged.
In the treatment rooms, the space is divided by the introduction of a visual horizon. While the lower part is assigned to the sterile, white working world of the dentist, the ceiling – which is the focus of the patient – is covered with an atmospheric sea chart on which there is constantly new territory to discover.

Schlossgut Bachtobel, Weinfelden
Master Plan, 2013
The Schlossgut Bachtobel, with its buildings currently used mainly for wine-growing, is to be revitalised gently and in a controlled manner through complementary uses of the historic buildings.
OOS was entrusted with the task of leading this process. After the development of the master plan, the innovations were translated into a spatial concept and the programming of the buildings was worked out as part of a preliminary project.
In a first stage, the converted tasting room was opened in early summer. Furthermore, parts of the listed substance are to be converted into a residential section as well as additional office space.
The Schlossgut Bachtobel has been family-owned since 1784 and combines historic buildings, forest, vineyards and meadows into a unique and valuable unit.

Novartis Cube Extension, Stein-Säckingen
Industry, 2013
Based on the functional needs of customers and users for a technical building with an office section, the architects generated a spatial atmosphere that derives from the relationship between technology and nature.
The usable floor space on the north side of the existing building (Cube I) was enlarged five times to a surface area of 10,500 m2. Due to the setting of the two units of the building, a new smaller space was created, which has had a positive effect, enhancing the overall spatial situation.
The artificial hill at the end of the building provides an attractive finishing touch, leading to a high-quality workplace in marked contrast to the surroundings dominated by industry.
The expansion was already under consideration during the development of Cube I so that it could be implemented without an additional development plan. The separation between the main building and the adjacent powerhouse strengthens its character as a campus, given further emphasis by the different colors of the facades. The logic and the sensory appeal expressed in Cube II are predicated on the analogy to a machine.
The cooling of the central spaces takes place through the facade. The air is drawn in through the facade on one side, and the heated air is released on the opposite side. In order to lend equal consideration to the technical and design specifications, the metal facade elements (metal panels) were folded. This ensures the stability and planarity of the aluminum elements held together at just a few points, even given the high percentage area of the perforations.

First District, Zurich
Education, 2012
OOS wins the study contract carried out by Priora for the southern construction site in the First District. Priora Development develops its extensive land reserve at Zurich Airport. The “First District” brand gives the entire development area a common identity.
In connection with the master planning in the First District, Priora Development launched a study commission in spring 2012 to gain important insights from a spatial planning and urban development perspective. OOS was able to convince the jury with its urban planning considerations and the long office and service building on the south site and win the study contract. The First District will become the hub between the city of Zurich and Zurich Airport and position itself as a business area with international appeal. Accordingly, OOS analysed the initial situation, values and vision and translated them into an architectural concept that meets the needs of corporate architecture. The 165-metre-long building sets an example and directly supports the positioning of the First District.

My Money Park, Zurich
Office, 2012
For the start-up My Money Park OOS has developed an adaptable design concept with a long-term focus that has already been implemented in the first Zurich branch.
The young financial advisory firm rethinks the advisory approach and puts clients at the centre of its considerations and objectives. OOS has translated the company’s values and positioning into a spatial environment that directly supports the new client advisory process.
In the entrance area, the client is guided to a pitch table where he or she can find out about investment opportunities. The personal advisory appointments take place in one of the eight “tree houses”.
The tables specially designed for MMP do not replicate the classic front-to-front counselling situation, but rather place counsellor and client in a partnership conversation at eye level with each other.
The cabins are covered with tree structures that create atmosphere and provide the necessary privacy with the curtain panels. The acoustic tarpaulins and carpets in the booths form a space within a space and a different acoustic situation; subdued, trusting, discreet. Further international locations are already being considered.

Swiss Embassy, Kamerun
Office, 2012
One of the defining elements of the new Swiss embassy in Cameroon is its walled setting. A key project leitmotif is walls in the form of tiers. Using this architectural device, the surrounding wall is integrated into the overall concept of the building complex.
Walls running from north to south create alternating interior and exterior spaces with a pavilion-like structure. This sequence of spaces establishes assignable spatial qualities. The alternating indoor and outdoor areas and the associated varying light mood and atmosphere create spatial sequences which are full of suspense. The compound represents values which are concomitant with Switzerland and Swiss architectural culture: security, strength, calmness, precision and openness. The atmosphere is determined by the serenity and presence of the walls which accompany and guide visitors through the building.
The horizontal configuration of the building makes use of the relatively steep incline of the terrain. Level 1 is where the “Chancellerie” together with the “Espaces de representation” are located. The degree of publicness is reduced as the building progresses from south to north. The private apartments of the ambassador and of his guests are located in the upper storey (“Résidence”). In the interior the materials applied are reduced, providing a clear and light impression according to the basic concept. The openings in the walls made of layered natural stone vary in their size depending on the intended use behind them. The facade gives a differentiated picture with a variation of light and shadow, while the warmth of the wooden partition walls and the wooden door and window frames contrasts with the brightness of the white painted concrete floors.

Showroom Allreal, Zurich
Culture, 2012
Allreal’s new showroom at the company headquarters (Eggbühlstrasse, Zurich) is tailored to the needs of prospective property buyers and endorses the company’s clear-cut brand profile.
Allreal pays special attention to the consultation process, which entails different requirements depending on the property. The new 95m2 salesroom is divided into zones by the walls. This contains niches for individual project windows in which the respective development is presented.
In addition to a digital screen, a range of fittings and sample drawers, a shelf is integrated on which the specific colour and material selection of the property buyers can be laid out and photographed. In this way, the customers can also let the personally made choice of the finishing standard have an effect on them at home.

Culture, 2012
Musicians and music lovers working and creating on 10’000m2 in the CLAUDIA – House of Sounds. OOS has been entrusted with the entire process from the positioning to the design development and realization of the eight stories building.
On the basis of transdisciplinary workshops and in close cooperation with the client our team has worked on the vision, brand values and usage conception for this ambitious project. Located at a prominent place directly at the highly frequented highway, rehearsal rooms, music studios, club, retail, event techniques and gastronomy will be gathered together in the same building forming a new cluster.
The positioning and the brand values as well as the programmation have been transformed into an authentic future-looking design concept. Like a front-stage, the façade will have an obvious impact on the appearance of the building. Using the reference of a stage, it will be calm at daytime and glamorous by night.
Inside (backstage) a hybrid mix of private and semi-private rooms bring opportunities for creativity and improvisation. Since autumn 2012 the house of sounds has become a lively place with interesting stories and illustrious guests.

Country House, Trélex
Special Housing, 2012
The new interpretation of the Vaud country house. The contemporary 2-family house integrates formally and visually into the rural environment and building tradition of the canton of Vaud.
On the site in Trélex, OOS is building a 2-family house with a total of 520m2 of living space. The challenge was how to establish contemporary architecture in the core zone of a picturesque village with a rigid neighbourhood plan. The new interpretation of the Vaudois country house can be seen, among other things, in the large, traditionally held roof form, which, however, jumps from the outer edge to the inner edge of the second house, thus structuring the body of the building and giving the volume that special “kink”. The “petite tuille vaudoise” roof shingles are constructed monolithically according to the old tradition. The large windows set into the façade reference the old manor houses.
At the client’s request, renewable energies and rapidly renewable materials are used in the houses. The consistent separation of the primary, secondary and tertiary structures results in a simple construction. The houses have solar collectors, which are used to generate hot water for the sanitary facilities and heating. In addition, a heat pump is used to compensate for the lack of sunlight in winter and to convert the cold air into energy.

Glattpark, Opfikon
Retail, 2011
OOS has been invited to take part in this competition with the goal of developing a block building in Opfikon that stands out due to its simplicity and creative sustainability. The concept has been developed in cooperation with Sichtraum.
The perimeter follows to the urban pattern and is built densely. The inner courtyard reaches the maximum extension possible and the different heights permit a well-balanced and optimized exposure to the sun. The colors on the loggias (balconies) implicate a lively atmosphere and structure the large-scaled front face. The apartments have a large entrée and are divided into rooms of similar sizes in order to gain flexibility for the individual preferences of the residents.

Armory Area, Winterthur
Master Plan, 2011
Together with Bednar Albisetti Architekten OOS was invited to participate in the competition for the Armory Areal in Winterthur. Different building structures in different scales meet at the Armory Area site. In its scale, the project refers directly to the large urban forms of the Armory Area and the surrounding buildings.
The basic urban concept is based on the idea of spatially differentiated outdoor spaces that include the existing workshop between the armouries on the site. These different, perceptible qualities of the outdoor spaces create specific and individual contexts for the flats with a clear address formation for the residents. The urban design is based on two building typologies: The row buildings with “thickenings” structure the outdoor spaces and the point buildings each act as a “hinge” to the adjacent plots.
On the inside, the projecting balconies reveal a lively, homely atmosphere towards the common courtyards. With different dimensions and materials, the balconies – together with the façade materialisation – ensure individuality and a high level of living comfort. Spatially, the flats are arranged around a large entrance hall, which serves as a switching zone between the large eat-in kitchen, the living room and the other rooms and underlines the generosity of the flat. The individual houses have specific themes, so that each building sets its own accents, conveys individuality and creates places of identification.

Landolt Area, Zurich
Special Housing, 2011
Urban life, independence and flexibility are buzzwords that appeal to committed singles and “dinks”. Good amenities and communications within the community are arguments for an elderly generation.
The area’s central position surrounded by the various development structures is fundamental to the project. The fragmented detached residences on Freudenberg meet with the uniform succession of various standards in the area of the Sihl River. Directly to the east, starts the perimeter block development of the city. The project combines the typology of point block building with the atmospheric density of an old town. The type of point block building enables the view of individual buildings to be specifically controlled and an orientation on three sides for each apartment.
In their proportions and formulation, the outdoor spaces refer to outdoor and intermediate spaces of an old town. These spaces are familiar and urban. Rather than the usual generic distance spaces, they are places of identification. Individual contexts with a clear address formation arise for each building. The principle of layering the spaces begins with the flats. The individual units are grouped around the access core in the centre of the building, which in turn develop around an inner core. Free floor plan design and different layouts are possible.

Pöyry Business Group Office, Zurich
Office, 2011
For the third time, Pöyry, one of the world’s leading engineering and consulting companies, has commissioned OOS to design a new office environment. In the Swiss headquarters, an area of 700m2 was converted on the seventh floor.
The goal was to create an inspiring working environment that represented the company’s identity. The corporate architecture elements developed by OOS were taken up again in the design concept and adapted to the new situation. Design elements such as the CI colour palette, the arrangement of the rooms, the lighting concept and the glass subdivisions were adopted and reinterpreted.
In order to present the five Pöyry business units represented on the floor, OOS developed a 45m long collage, which fits into the existing corporate design as a new, identity-forming element and highlights the company’s values. The pixelated elements of the collage were designed using Parametric Design Tools, printed on foil and applied to the wooden panels. The new design element adorns the walls along the entire floor length and connects the five business areas.

KA BRU FOREST, Itacaré BRA
Special Housing, 2011
Located in the Atlantic rainforest (Mata Atlantîca) south of the state Bahia the holiday accomodation KA BRU FOREST blends into the particular ecological system of the paradise like environment.
The interior of the holiday home is divided by platforms of different heights and structured according to use. The floor plan translates the structural requirements and technological possibilities into a surprising architectural system that faces north and guarantees optimum solar radiation and shading.
For transatlantic cooperation, a simple construction manual is sketched out. The virtual 3D model is implemented directly on site with the available materials without the help of classical construction plans. Traditional types of construction are reinterpreted; for example, the roof is made of palm leaf wickerwork and blends with the vegetation of the hillside location. The house is ecologically self-sufficient.

Service Center Novartis, Basel
Industry, 2011
The Office and Service Centre planned and implemented by OOS at the Klybeck Plant in Basel is located directly on the Rhine River and provides a wonderful view of the river and the Novartis Campus on the other side through its glass facade.
The structuring of the facade using a filigree grid pattern gives the seven-story building its specific character and simultaneously integrates it into the urban ensemble of its environment. The anodised aluminium frames consolidate the artistic and technical aspects into one element. The appearance changes from maximum transparency to a completely closed-off cladding.
The building consists of two sections that are used for different purposes. While the lower floors feature the requirements for a technical building unit, the upper floors are designed as office space and offer a contemporary work environment for about 220 employees.
The central area is furnished as a multi space and structured with smaller meeting rooms, informal meeting zones and telephone alcoves. The large meeting rooms are located on the short facades.
The communication zones facing towards the Rhine provide break room facilities thanks to their kitchenettes. A bench along the façade invites informal exchange among employees and simultaneously gives the room a clear demarcation.

Mythenquai Lido, Zurich
Culture, 2010
The sandy beach sets the Mythenquai open-air swimming pool apart from all other baths in the city of Zurich and represents a unique offer. By extending the beach area, this specific quality is reinforced and the profile of the lido is sharpened.
The superimposition of two moods, that of the sandy beach and the classic northern European tree landscape, creates a new flair in the Badi that defines the park. The valuable and protectable tree population is preserved and knitted further in the sense of the existing structure.
The poetry of the tree formations develops into the formal language of the building and the roof. The filigree appearance of the roof and its soft forms allow a harmonious integration into nature. Through the addition of underlying circular shapes, the roof is not perceived as a clear line and the length is reduced in perception to the respective segments. The building itself allows for (unexpected) views of the lake and the mountain panorama time and again through the distribution over two volumes and through the complete openings of the façade in the public area.

Showroom Richti Area, Wallisellen
Education, 2010
With a showroom, Allreal informs about the urban development and the offered uses for retail trade and residential property in the new Richti area.
In order to best present the identity of the future Richti area, OOS developed a multidimensional concept of a showroom. Here, the atmosphere created in the Richti area is to be conveyed as realistically as possible. This is achieved by using authentic materials, digital media, lighting moods, scents and an audio installation that stimulates the viewer’s senses in a restrained but unique way and creates an overall mood.
The urbanistic ground plan (situation) and the atmosphere of the Richti area are recorded in the interior of the showroom via the themes “Hof – Gasse – Platz”. At the centre of the showroom is the 1:200 model of the area, which, at 2.50 x 3.00 metres, shows a very realistic picture of the future structure and environment and on whose surface additional information such as different sun positions and seasons or traffic flows are simulated “realistically” with a video projection.

Maria Aguilar Hotel, Península de Ancón CUB
Hospitality, 2010
The hotel of the 21st century – urban planning, architecture, landscaping, scenography and interior design stage an environment that is unique in the entire Caribbean and sets a benchmark for future buildings in and around Cuba.
In order to be able to arrange the rooms of the hotel optimally, a special software was developed. The main criterion for this optimisation was to orient each room towards the sea or, if this is not possible, to create a larger room towards the park. Other parameters determined the minimum distances between the rooms and the number of rooms per building, as well as the direct sunlight. The optimization process is based on a generic algorithm that analyzed the layout of the hotel and changed it through several iterations.
The design is an architectural expression of the relationship with Cuba, Trinidad and the local environment; elegant and relaxing at the same time, it is contemporary, attractive and functional. It is the result of a mixture of existing Caribbean architecture and a reinterpretation of colonialist architectural elements. The design emphasis, such as colonnades, terraces, pergolas, facades, gardens, curtains and Cuban art, evoke an amazing architectural ensemble full of character, somewhere between Caribbean and contemporary architecture.

Fashion History Museum, Tokyo JPN
Culture, 2010
In this concept competition, OOS has shown its own interpretation of fashion as a communication vehicle. The visitor is an observer and becomes the object of observations, too.
The Tokyo Fashion History Museum is a kinetic building consisting of 21 movable exhibition boxes. During the “museum trip” the museum visitor can walk through the differently staged exhibition boxes, enjoy the view of the city and observe the passing scenes of visitors and exhibits.
The concept eludes a strictly chronological exhibition dramaturgy, because the sequence of rooms changes at any time by changing to another exhibition box. The performative character of the building intensifies the experience of the museum visitor and attracts the attention of the public. The museum is both stage and tribune, the museum guest actor and spectator.

Showroom Albert Reichmuth, Zurich
Retail, 2010
“LA GALERIE DU VIN” is both a sales and a tasting and seminar room and is able to appeal to regular customers and passers-by alike. The OOS room concept picks up on the company’s values and traditions and focuses on the wine bottles.
The interior design aims to create a strong image of a landscape made up of wine crates, in which the quality wines are presented like in a Schaulager with their crates. Around 1,500 unbranded wine crates from the Bordeaux region cover the entire room up to the ceiling and form a grotto-like environment.
Arranged in a grid, they serve as a platform for around 570 wines, illuminated table showcases as well as books and seats. In the middle of the room, the reception is situated as a counter, equipped for wine purchase advice and with its violet/ruby tone contrasting with the wood of the wine crates. The lights on the ceiling are formally oriented to the wine bottles and integrate into the presentation of the wine bottles.

The new headquarters of the pension fund “Nest Sammelstiftung” reflects the ethical-ecological corporate values and conveys a future-oriented image. The project comprised a roof extension with an additional office floor and the interior finishing of the three upper floors. The result was achieved in close cooperation with Bureau de Bank (Holland).
The office environment is based on three principles: a contemporary working environment, a networked organisational principle and the theme of “nature” as a translation of Nest’s ethical-ecological values. At the beginning of the conception phase, the working methods and needs of the individual departments were examined and translated into different floor plans over the three floors. The office space is divided into official and informal zones. In order to promote active collaboration, the three floors were vertically connected by an internal spiral staircase.
The structural conditions of the existing property and the specific needs of the users were conceptually brought together in various principles taken from nature. Thus the section through the three office floors of Nest is also a cross-section through nature – earth (lowest level), forest (middle level) and sky (highest level) were used as identity-giving design principles.
In addition to the structural translation of this section into layout and workplace, the image also serves to select the colour and material of the respective floor. The open space in the different departments was structured by cabinet walls and overhead shelves.

Novartis Cube, Stein Säckingen
Industry, 2010
The multilevel house is designed as functional building and lies in the middle of an industrial zone. The concept shows an abstract industry architecture based on a cube and above-head pavilion.
The simple, compact building geometry of the Cube results from the functional arrangement of the rooms, which allows for future expansion without additional access zones. The working environment on the top floor has a pavilion-like quality due to its visual embedding in the wooded hilly landscape, the fading out of the immediate built environment and the relationship between the interior and the terrace area.
The expression is strongly influenced by the technical requirements. Clear specifications for different degrees of opening in different zones are translated into a homogeneous façade that spans the building body and oscillates in its appearance between volume and dress. By folding, the sheets gain stability and allow an unexpected freedom of design despite high degrees of opening. “Parametric design” helps to control the perforation of individual elements, their arrangement in the façade image and the direct translation into production.

Museum of Transport, Lucerne
Culture, 2009
With a permanent exhibition over an area of 1700 square meters in the Road Transport Hall, the Swiss Museum of Transport in Lucerne presents the history and future of road transportation. In close cooperation with 14 exhibition partners from the automobile industry and the Museum of Transport as client, OOS has staged an exciting exhibition.
At the beginning, there was the idea of an overall concept that shows the history of road traffic. Together with the museum management, OOS developed ideas for the individual theme islands and presented them to the future sponsors.
In this way, OOS was able to take the lead in ensuring that the exhibition was holistically conceived and implemented, from concept development and financing to the detailed planning of the individual thematic islands, the search for and integration of the exhibits and the development of the graphic concept.
The individual exhibition themes are translated into design metaphors and are recognisable in spatially insular, individually designed exhibition buildings. Different experience offers and the spatial overlays take into account both the cultural interests of the Swiss Museum of Transport and the commercial interests of the sponsors and financing partners.
From graphic illustrations to large media projections, different media are aimed at a broad target audience, consisting equally of car freaks, families, small children and senior citizens. The diversity and complexity stimulates the visitors’ imagination, encourages associations and leaves room for interpretation.

EXIL Musik Club, Zurich
Culture, 2009
The live music club Exil is conceived as a “black box” and can be staged in different ways depending on the event or concert.
The sequence of rooms on the ground floor already begins in pitch black. The only differences are the materials of the surfaces: The fleecy carpet contrasts with the shiny, smooth surface of the artificial resin, while the relief surface of the matt walls is covered in a shiny varnish. The bar made of massive oak beams sets the tone. Behind it, the metal curtain creates unexpected light reflections.
All conversion measures on the ground floor address the spatial acoustics and create excellent, harmonious sound conditions. The smoking room adds a contrast with its Bordeaux colored carpet. From the mysterious, dark world on the ground floor, one descends to a surprising array of bright, neon-colored rooms one floor below, with monochrome abstractions that create a completely unexpected spatial experience.

MYSTOP Motorway Service Area, Knonaueramt
Retail, 2009
OOS was given the unique task of developing a brand concept and the brand environment based on it for the motorway service station on the N4. The OOS-led team of graphic designers, catering specialists, lighting designers and sound and scent specialists planned and implemented the concept.
The brand was developed on three levels and in three steps: In a first step, the brand values were defined in a target group-specific needs analysis: individual, intelligent, tailor-made. Then the brand name was developed: The name “My Stop” reflects the service-oriented approach of the service station. This is underlined with the brand-specific font. In the third step, the concept for the exterior, façade, interior (access/retail/catering) and signage was developed and the brand values were spatially transferred. The service area is a place to stay and a meeting point with individual offers geared to different needs.
The implementation focuses on the interior fittings such as entrance areas, My Stop shop, takeaways, My Stop zone, restaurant with back office and storage areas as well as the visitor guidance in the interior. In order to be able to fulfil the goals of an overarching planning of atmosphere and brand presence, these considerations were gradually merged with the design of the corporate identity.

Station Square South, Winterthur
Public Buildings, 2008
Far more than just a bus station, the station square of Winterthur’s future is an interface in public space.
The situation calls for a clear intervention which, through its scale, enters into dialogue with the surrounding urban bodies, abandons the small-scale approach and orients itself towards industrial and infrastructural architecture.

Office Liip, Zurich
Office, 2008
A tailor-made corporate environment was designed for the new headquarters of the web development company, which accommodates 22 workstations, two meeting rooms and a lounge on an area of 400 square metres.
The workplaces are not only located along the windows for lighting purposes, but also to generate a generous open space in the middle of the room. The system is structured in such a way that it can be used in various configurations for the display of movable furniture in the room.
The main room, where the workplaces are located, reaches all the way to the entrance area and is characterised by the special way the wall surfaces are handled, in addition to the black reflective floor. On the one hand, the tapestry creates pleasant room acoustics and, on the other, forms the main identity-creating element of the company.
The pattern of the carpet was created with specially developed parameterisation software. This was formed from overlapping layers (location, incidence of light, sound, corporate colours) that are directly related to the company. The meeting rooms are designed to be brighter and calmer as a contrast to the stimulating work zone. The silver sprayed ceiling runs through all the rooms as a connecting element.

Swiss Pavilion Expo 2010, Shanghai CN
Culture, 2008
Everything is based on comparisons. What is Switzerland, what is China? What is typically “Swiss” about Switzerland, what is “Chinese” about China?
In an increasingly globalised world, there is a growing need on the one hand to compare the “own” with the “other”. At the same time, it is becoming more and more difficult to make unambiguous classifications. In the daily exchange the common prevails.
Cultural opposites from the past are being transferred to museums or become popular souvenirs. The Swiss Pavilion at the 2010 World Exposition presents Switzerland as a globally networking country with a long tradition of international exchange in science, research and culture.
In a playful comparison between China and Switzerland, the predominantly Chinese public is introduced to the largely unknown country as a remarkable place of ideas and inventions in the centre of Europe.
For foreign visitors, European and Swiss guests, the performance builds a bridge to the great historical achievements of Chinese culture and the economic successes of today. Switzerland’s experience: Cultural and economic progress is always based on intensive exchange and mutual stimulation, and China also plays a central role in this.

Engadin Airport, Samedan
Hospitality, 2008
The characteristic light of the Engadine, the soft valley floor, the sharp mountain – pointed, coloured larch forests, the ice-cold waters of the Flaz and Inn, the white-blue glaciers, the clear sky – these surroundings form the framework for the architectural project, which is locally grounded and at the same time directed towards the modern style of the “big wide world”. Nature and environment are the inspiration for the architectural themes.
The building unites and interprets opposites in both a direct and a figurative sense. The airport’s heterogeneous target group benefits: The new building is not a boring Disneyfication of alpine architecture on an oversized scale, but an authentic interpretation of the existing environment. The aesthetics of the airport interprets the existing environment in a differentiated way and thus enables a new view of the existing beauty of nature, away from clichés and brochure motifs.
Together with its surroundings, the airport is a strongly distinctive element of the valley plain and stands out in its scale from all other architecture in the Engadine. As a welcoming gate for arriving guests, an attractive programme point in the region for tourists and a place to work for locals, the building will become an important representative of the Engadine.

Pöyry Infra Headquarter, Zurich
Office, 2007
For its headquarters in Zurich, the engineering office needed around 33 additional jobs on an area of 560 square meters.
The meeting rooms and focus rooms (for “standing”) divide the open-plan office into zones, while the workplaces are located in the areas with good daylight. Despite the hard floor, the textile-covered ceiling panels with mineral wool filling ensure pleasantly muffled acoustics.
The focal spaces and installations on the ceiling do not follow the strict exterior geometry of the building in the longitudinal direction. If the viewer shifts in the space, the overlays on the ceiling and the reflections in the non-orthogonal glass surfaces start to move.

Airport, Zurich
Master Plan, 2007
On the premises of Zurich Airport, the clearly defined zones will be given a new identity.
Infrastructure (old) + atmosphere (new) = “Infrasphere” These zones provide orientation points for airport visitors, increase their sense of well-being and shape their memories.
1) Brand screen Gate to the airport. Rear becomes front. During the day: Face of the airport. At night: Europe’s largest advertising space. Textile on steel.
2) Arrival lounge, first contact with Switzerland. Warm welcome gesture. Tidy and bright. Clear and cosy. Luminaires as objects in the foreground. Illuminated wooden screen as background.
3) Departure lobby, farewell to Switzerland. Reception of guests. Cosmopolitan and inviting. Protective and organising. Wooden screen with a view.

Christmas Lights, Uster
Culture, 2007
With a poetic translation of the Christmas theme, the constellation USTER brings light into the darkest time of the year and appeals to the population on various levels. The OOS concept achieved 1st place.
Spherical lighting elements of various sizes are being suspended into the skyline above the streets of the centre of Uster. At six different locations, these luminaires form known constellations, which can actually be observed in the December sky above Uster.
The luminaires consist of a spherical frame, which is hung with highly reflective aluminium plates. The light emitted in all directions from the centrally positioned light source via a prism glass makes the metal plates glitter. Sound elements brought to sound by the wind turn the constellation USTER into a synesthetic overall experience for locals and visitors.

Maag Recycling, Winterthur
Education, 2004
The building structure presents itself as an urban fit. The expression and form of the new building are a reaction to the existing urban situation and a clear interpretation and distribution of the five programmes: recycling yard, storage hall, workshop, park and parking deck.
The idea of “reverse shopping” creates a new offer for urban society that picks up on the zeitgeist of the circular economy. The tension between conventional and industrially prefabricated materials characterises the building structure.
It is the tension between raw, prefabricated concrete – the primary structure – and the galvanised diagonal mesh, which is superimposed on the body and fulfils various functional and aesthetic aspects and demands.
It protects against break-ins into the hall, which is filled with valuable old materials, serves as a fall protection and at the same time forms the individual character of the new building. Depending on the angle of view, it appears completely transparent, allowing the pure, raw structure to come to the fore, or it forms a solid body from the volume.

s-cape KKL, Lucerne
Culture, 2004
Installation during the Eurovision 2004 Young Musicians at the famous KKL Lucerne.
“Anyone who dares to cover Jean Nouvel’s prestigious building with an installation either has the courage or a large portion of impertinence,” we were told on several occasions, “but s-cape is appropriate for the Culture and Congress Centre Lucerne. s-cape has managed to breathe life into the building and enchant it. The comments of visitors to s-cape say everything that the installation is intended to achieve and convey.
Together with sound architect Andres Bosshard and under the patronage of Swiss television, OOS has created a place that invites people to linger for the duration of Eurovision 2004 Young Musicians. As a place of encounter, dialogue and dreaming, it occupies a permanent place in the scenographic and content-related centre of the event and conveys its values.
Under the KKL, the sound space s-cape also lies in the immediate physical centre of the festivities. s-cape uses sophisticated technology to diffuse the sounds from the inside of the KKL into the outside space. The tones, notes and sounds escape from their architecturally impressive projecting canopy of the corset and merge in a modified form as a sensual surprise with Lucerne’s urban space.

Bar Rossi, Zurich
Culture, 2004
In order to allow gastronomy and culture to unfold in a contemporary atmosphere, a lighting and room concept was developed which “reacts” specifically to the different requirements (café, restaurant, bar).
Daylight and artificial light determine the atmosphere in the interior throughout the opening hours; during the day, the café and restaurant is a fresh, sharp-edged and clear continuum of space. At night it is a bar, where the room becomes an intimate and multifaceted living room
Dark parquet flooring and bar furniture, copper shimmering glass, metallic and beige tones in the furniture and wallpaper give the Bar Rossi its unique warm ambience. Bar Rossi has 35 seats, 8 bar stools and a small lounge. Together with the distinctive bar furniture and a pedestal, which is also a stage for concerts and performances, the lounge forms the setting for the Bar Rossi. The two large front windows can be fully opened to the outside.

House Schudel, Feldis
Special Housing, 2002
In order to provide an optimal view of the Alps, the building makes maximum use of the property. The form is the result of a subtle manipulation of a simple body that is transformed into a wooden sculpture.
Depending on the point of view, the monolithic building is sometimes narrow and light, sometimes wide and heavy. The residents change the expression of the building by opening and closing the large-format shutters.
Inside, a cascading staircase tracing the slope leads into the large open living room. Rooms of various sizes and geometries maximise the experience of a spatial atmosphere. Each window frames a precise image of the landscape.

Sound Tower Expo.02 Arteplage, Biel
Culture, 2002
The sounding landmark of the Expo.02: the shell of one of the three towers on the Arteplage Biel designed by Coop Himmelb(l)au becomes the carrier of an interactive musical instrument.
A unique loudspeaker constellation creates a virtual, “kaleidophonic” acoustic. Vertical vortex movements are the basis for the projection of various sound experience spaces, which are perceived as a constantly breathing sound stream. The sound stream is based on a weekly composition.
This reacts on seven different listening levels to the events in the surroundings and is changed and designed live by musicians. In the dynamic sound stream, the musicians perform live with their own instruments. The capsule serves the musicians and sound architects as a “concert ditch” at a height of three metres. It can be opened and closed like a cocoon. The ceiling becomes a stage when opened.
The artistic concept of sound architect Andres Bosshard was planned and realised in collaboration with OOS, sound specialists and musicians
