The six roughly 40–45 m² flats on the standard floors consist of a basic type – with slight variations to the corner dwellings – laid out on both sides of a naturally lighted 2.10-metre-wide central corridor. Outside the entrances to the dwellings are fold-out tables that can be arranged by the tenants, thus lending a sense of identity to the environment.
The electrically operated fire doors at both ends of the corridors stand open and allow cross-ventilation and views of the city. The staircases are situated directly next to the facades to avoid creating dark internal access spaces. They act as viewing platforms and thus promote contacts between residents.
A specially designed graphic directional system serves as a means of orientation in the building, and the retro-look patterns on the walls of the communal spaces are meant to suggest a familiar atmosphere.
Even from a distance, the structure of the tower is clearly legible. Its outer appearance is dominated by the communal spaces, the staircases on the outer faces and the colours of the dwelling groups. Corrugated and expanded metal elements are a further feature of the facades. In order to construct the two-storey glazed corners of the communal spaces without columns, the east and west facades were designed as load-bearing cross-walls with window and door openings. The dwellings are tailored to the needs of senior citizens, who nevertheless lead largely independent lives. A contact point exists in the block for medical and household services and to organize joint activities.
