To allow the neighbours an unimpeded view of the Greifensee, a nearby lake, and to create a parking space on the tight site, the northern part of the house is asymmetrically cut away on both sides. Depending on the viewpoint, the irregular geometry conjures the impression of a building with a single-pitched roof or of an expressive wedge-shaped form. The loft-like spaces on the first floor are daylighted via a window strip that follows the angular line of the eaves. Local building by-laws specify vertical rectilinear openings, however, so that the architects opted to conceal the windows behind an external screen of spaced pine fins. This open form of cladding was omitted in the area of the sliding door to the terrace to allow an unimpeded visual link with the outdoors.
