Apartment House Frame, Andermatt
Special Housing, 2020
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.

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.

House Uto, Zurich
Culture, 2025
OOS has been commissioned with the refurbishment of the historic ‘House Uto’. The aging housing stock will undergo a core 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 refurbished to its former glory and will be listed as a historic monument in the course of the refurbishment.
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.

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.

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.
