Located in the Fribourg municipality of Wünnewil-Flamatt near Bern, the exposed concrete box on stilts is sandwiched between the Sense and Taverna rivers. The south-facing building comprises five residential units and a studio apartment. With the roof terrace and external staircase, as well as the bold colour scheme by artist Rolf Iseli, the guys from Atelier 5 openly quote their stylistic idol Le Corbusier. In contrast to the rough exterior, the spacious interiors are painted in an immaculate, modernist white, and the floors in the living room are made of Spanish clay. Flamatt 1 is a listed building of national importance.
