This modern, transparent residential building was planned as a replacement building for a plot in a prime location with direct access to Lake Zurich. The side of the building facing the lakeside is completely glazed; the living space offers direct views of the water. A wall delimits it clearly from the predominantly public, adjacent space. The floor plan pivots on a central spiral staircase, which runs through the entire building along an airy space. The individual rooms are arranged around the staircase.
