Single Wall House
Outwardly simple, this project is, in fact, rather sophisticated, both structurally and spatially. On a small and narrow plot, overlooking the heart of Zurich, the architect has built a structure containing two houses. Instead of sitting them one above the other, or in tandem, the volume has been split vertically and longitudinally, so that each dwelling can take equal advantage of the views. The parting wall zig-zags and follows a different line on each of the three floors. This stabilizes it transversely and maximises the variety of spaces, which flow from floor to floor via open stair flights. The wall is formed in reinforced concrete as is each floor plate, which is cantilevered from it, so that there are no perimeter columns to obstruct the views. The above ground external walls are completely glazed; some sections can be slid open for ventilation. External roller blinds located along the edge of the floor slabs can be lowered to control solar gain and help with privacy.
