Plot B3 south is interpreted as a small housing complex.

From a generously proportioned, shared lobby, two stairwells each provide access to four residential units per storey. A half-storey offset between the two halves of the building results in different room heights on the ground floor. The ground floor has a room height of 4.3 m towards Spinnereiplatz. It is home to a bakery cum café and the common room for all non-profit housing cooperatives on the site. Smaller studios are located in the northern section of the ground floor with a room height of 3.6 m.
