the residential building is located on a steeply sloping site in the halbhöhenlage („halfway up the hill“) area of stuttgart. the geometry of the grounds and the fine views dictate the basic shape of the building: the conical structure lies at the heart of the design concept. the living areas all face out over the view, and a large window spanning two floors frames the panorama like a picture. the roof is a gable roof with a sloping ridge and reflects the shape of the ground plan. the spacious entrance floor with garage and secondary apartment is built discretely into the hillside.
