extension of the water department building

Competition

The proposal was to continue the typological logic of the existing building. But, to ensure ecological continuity on the ground (small mammals, insects and other small inhabitants of the earth), the extension was planned on posts, leaving the ground completely free. Not compact enough, they said. Not sure that an artificial crater for concrete foundations would be more ecological. But the discussion is worthwhile.

Competition

We were the only team among 40 participants to propose keeping the existing, fully functional school. And this against the (mainly economic) recommendations of the client. What do you call this? Suicide or coherence? Ask the jury.

Design for care

Medical facilities have traditionnally been visually sterile and consciously neutral.

This refurbishment of a medical practice on a very tight budget allowed (or forced?) us to negotiate with the existing structure and the technical modifications of the 1970s.

Suspended ceilings and plaster partitions have been removed, exposing the organs, veins and bones of the building. A new skin of sprayed plaster covers them like a veil, producing an inspiring surface to look at, while the practicioner is examining your body.

In the access corridor, mirrors mounted on the doors create an fascinating game of depths and counter perspectives, challenging the very classical layout and giving the patient a time to reflect before entering the medical practice itself.

saas sàrl produces architecture since 2012. Drawn or built, this architecture means to be vital, understandable, powerful, multiple in its lecture but simple in its appearance. Based on a research about plasticity and the study of proportions, it is spatial, physical and hence, built. Deeply convinced that architecture and the city are collective works, the office draws its strength equally from the interactions with users than from the professional collaborations, local or international, that might arise.
saas sàrl has so far mainly focused on questions of transformations, that be on the urban or architectural scale. Mutating urban context, jumps in scale, structural mix and complexity, morphological and typological researches are at the core of our practice. Shifting conditions and evolution are given variables and stable companions.
saas sàrl has been lucky to work for private individuals as well as collectivities, from the transformation of a single family home to the reconversion of an oil refinery. The office has been working with entities such as CICR, SIG or BONFED. Its works have been presented at the S AM Basel, at the F’AR Lausanne and the Architektur Salon in Hamburg, among others.

Guillaume Yersin (Vevey, 1981) studied Human Medicine at the University of Geneva. After obtaining a Bachelor in 2003, he then studied architecture at the ETH Zürich and at the Tokyo Institute of Technology. After experiences at Lacaton & Vassal in Paris and AMO in Rotterdam, he obtained a MSc. in Architecture from ETHZ in 2009. In 2012, he founded his own practice saas sàrl in Geneva. In parallel, Guillaume maintains his academical engagement as intense as possible. From 2012 to 2016, he has been a teaching assistant to the Prof. Christ & Gantenbein at ETH Zürich. He has been repeatedly invited as a guest critic at EPFL, HEAD, ETHZ and HEIA-Fribourg. In 2021, Guillaume was invited as a guest professor at TU Wien. He is currently Guest Professor at the FHNW in Basel.
