The Hermann-Dorner-Allee residential quarter in Berlin-Adlershof addresses one of the central challenges of contemporary urban development: the creation of affordable housing without compromising architectural quality, social diversity or environmental performance. Developed for the municipal housing company HOWOGE and designed by blocher partners, the project forms one of the largest residential developments in the company’s history.

Situated at Berlin’s science and media hub Adlershof, the quarter occupies a site of approximately 27,000 square meters and comprises 11 buildings with a total of 505 apartments, 108 student units, integrated commercial spaces and a daycare center. A key objective of the design was to foster social mix: subsidized housing is distributed across all buildings, encouraging diversity and avoiding spatial segregation.

The urban layout responds sensitively to its surroundings. Closed perimeter blocks along Karl-Ziegler-Straße define a clear urban edge, while quieter inner courtyards provide protected communal spaces. Semi-open arcades shield residential units from traffic noise, and the ground floors are articulated by generous arches referencing Berlin’s historic railway architecture, inviting informal encounters and everyday interaction.

A modular and standardized construction system formed the basis for an economically optimized yet expressive architecture. A limited number of predefined modules and materials are combined in varied ways, resulting in differentiated façades and distinct building identities. Each building typology follows its own design concept, ranging from colored plaster finishes to timber façades, reflecting the heterogeneity of the community itself.

Sustainability plays a central role in the project. Photovoltaic systems installed on all buildings generate CO₂-free tenant electricity, while decentralized heating and hot water systems ensure energy efficiency and reduced resource consumption. Generous green courtyards, extensive bicycle parking and provisions for e-mobility further support a future-oriented, livable urban environment.
