Three new residential blocks were constructed in the Cordierstraße area of the Friedrich-Ebert-Siedlung to replace obsolete existing buildings. They were based on an urban design and architectural study prepared by AS+P for ABG FRANKFURT HOLDING in spring and summer 2014, which explored a measured densification of the existing site.

AS+P developed the study and designed three six-storey, linear residential buildings comprising a total of 129 apartments. The task combined the replacement of the three existing blocks with a measured increase in density at broadly the same location and alignment. The site’s particular topographical conditions also had to be addressed in the design.

The plots lie approximately two to 2.5 m below the level of the surrounding streets, creating particular requirements for step-free access and escape routes. The east–west-oriented buildings are connected at their southern ends by a parking structure providing 48 spaces. Its roof connects almost level with Cordierstraße and forms the access routes to the residential blocks. The buildings were constructed to Passivhaus standards and feature planted flat roofs.
