The blocks at Crednerstraße 2-12 and Zweifelstraße 1-11 have been built parallel. They each have 6 entrances, three flats per floor. The upper floor with the small windows is used as an attic. The block at Zweifelstraße 13-19 is shorter and has four entrances. The design is the same as for the two longer blocks and all houses are masoned.
The streets were used as an orientation for the entrances to the houses. The balconies are located on the sides facing the courtyards. This means that the balconies in Zweifelstraße face east, while the balconies in Crednerstraße face west.
The Heritage Institute describes the houses as "Schlichtwohnungen" (schlicht - simple/plain), which is probably meant to describe their spartan or simple furnishings.
