Flamatt I counts as one of the first and most influential brutalist residential buildings in Switzerland. The terraced-housing plan redefined and simplified «béton brut» Le Corbusier design concepts for the Swiss habitat and put Atelier 5 on the international map.
Located in the municipiality of Wünnewil-Flamatt near Bern, the box-on-stilts in exposed concrete is sandwiched between the rivers Sense and Taverna. The south-facing building comprises 5 single-family units and a studio-house section. With its rooftop terrace with stair and vibrant colour scheme (by artist Rolf Iseli) and other design details, the building cites various signature Le Corbusier-isms. At the period, Flamatt I was fêted as a masterclass in low-cost construction and high-standard living. The building also reiterates similar plans the studio used for their single family house in Rothrist (AG) and the Boiler Factory in Thun (BE), both completed in 1958.
