The two-storey detached house is set on a hill in a suburb of Basel. Various projections and set-backs together with rounded corners with varying radii lend the building a sculptural and dynamic appearance. This is accentuated further by the use of simple concrete throughout and by the varied shapes of the many openings. The windows on the north, west and east sides are set behind small round openings in the façade, which thus acts as a filter. The south side by contrast opens up with large picture windows and glass doors. The round shapes continue on the interior, creating exciting sequences of spaces. From the living room a spiral staircase leads to the upper floor, which features a curving gallery, four rooms, two bathrooms and an open office area. A roof terrace with a view is accessed via a staircase attached to the outside of the building. The lower level accommodates a guest room and a generously sized open multipurpose room. Both draw daylight from a courtyard. In the interior, plywood boards of maritime pine, raw steel, concrete terrazzo flooring and exposed concrete walls create a sleek, low-key ambience.
