The newly built residential quarter Bautzener Straße in Berlin-Schöneberg comprises seven buildings with a total of approx. 300 residential rental apartments, commercial uses on the ground floor and 1st floor as well as a large fitness studio and a day-care center.

Our master plan specifically addresses social and energy-based aspects of sustainability. The urban design relates to the building typology and building heights of the surrounding neighborhood. The design is characterized by an interaction with the buildings south of the Bautzener Straße; an interplay of building mass and open spacial situations on both sides of the street—varied but an orderly urban space. The building mass is permeably divided into individual buildings and creates a tangible spatial connection to the large city park in the east on the other side of the railway line.

An innovative system makes it possible, among other things, to heat the entire quarter under normal conditions exclusively with heat extracted from a sewer pipe and solar electricity. Gas as a fossil energy source is only used as support in extreme winter temperatures. Controlled mechanical home ventilation supplements the option of window ventilation and allows heat recovery as well as nocturnal noise protection. The project has won awards for its energy-saving, sustainable design.
