The new building consists of three cubic, eight-story townhouses on a square floor plan. They form an urban and typological contrast to the ten-story residential lines, which look very hermetic. The courtyard room thus retains its original green spaciousness. The staggered arrangement of the houses creates wide-ranging visual relationships and differentiated open spaces. The new buildings are accessed via a central neighborhood square. The lowest living level is arranged like the existing mezzanine buildings. Only the day care rooms in the southwestern cube on Dolgenseestrasse are connected at the same level by giving them a special height and avoiding the need for a basement.
The houses are very economically designed as five-in-hand cars with internal stairwells. A total of 117 apartments, 2 shared apartments and day care are planned.
