With the Parkquartier, a varied residential square was created between Steglitzer Damm and Steglitz City Park in the middle of the green district. The project includes sustainable urban repair through subtle additions, conversions and modernisation of an existing residential complex. By converting the existing building from the "exposed aggregate concrete era" of the 1960s, building over a supermarket and redensification, a total of 101 high-quality apartments were created from the original 45 residential units. The development of the supermarket, including the reinforcement of the supports and foundations for the building suspended above it, took place during ongoing operations. Three newly added apartment buildings, grouped around a green courtyard garden, which are oriented in their size and design to the surrounding buildings, complete the existing structure to form a closed building scheme. With a range of one- to five-room apartments, the new block of houses will meet a variety of living requirements. In addition to classic floor plan variants, individual and modern living solutions with open kitchens, generous living areas and variable individual rooms are offered. Furthermore, almost every apartment will have a generous open space in the form of a balcony or terrace.
