Two streets, Alte Landstrasse and Pilgerweg, frame this newly-built multiple-family residence in Thalwil. The horizontally-oriented building, thanks to its self-assured elegance, fits in harmoniously with this environment at the town's center. It accommodates a total of seven apartments, one among them a rooftop apartment. The actual apartment boundaries are recessed from the exterior walls. The exterior space thus created removes the boundary between the interior and the exterior while protecting privacy. The stairwell is airy. During the day, the apartments show a certain noble reserve; in the evening, the volume becomes a luminous body radiating life and openness. The horizontal layers, set apart from one another, are permeable, from the eastern side of the house facing the lake with its large loggia to the western side facing the hillside. Stainless-steel supports and concrete walls mark the house's boundary at the edge of the street and the adjacent property.
