Wald-Ring-Quartier
Conversion of the Sindelfingen Hospital Site
Inclusive, climate-neutral, interconnected, and diverse: Our design for the competition provides a comprehensive answer to the question of how we want to live in the urban fabric of the future. An independent urban module with a distinctive identity repurposes existing structures to create a new home with high-quality living spaces.








A loop as a connecting element
A vibrant quarter with forward-thinking residential and usage concepts is set to emerge on the former hospital site in Sindelfingen. Together with ensphere, our specialist planning office for landscape and urban design, we developed a concept that integrates diverse usage requirements, functional demands, and extensive ESG factors into a cohesive whole. At the center of this vision is the human being – connected to the surrounding environment and in harmony with nature.

With the Loop, we integrate significant historic pathways into the vibrant structure of the new quarter, which will combine residential spaces, educational facilities, and recreational areas while respecting nature.

A nature-oriented microcosm
Expansive green and open spaces enable a harmonious connection between people and nature. As an "edible quarter," the area offers diverse garden formats – both private and public – including spaces for urban gardening and associated educational initiatives.

The biophilic quality of the concept enhances the quarter’s resilience, fosters biodiversity, and promotes the well-being of its residents. Overall, it strengthens both social interaction and a connection to nature.

The Wald-Ring-Quartier fosters a socially diverse community. Distinctive landmarks and strategically placed access points improve orientation within the quarter’s structure. A well-balanced mix of residential, educational, and service functions creates a high-quality living environment. Numerous green zones define the area’s boundaries, merging the urban space with the surrounding forest. This new connection makes the "New Urban Green Deal" a tangible reality.
Resource conservation, energy efficiency, and circularity
A commitment to preserve the existing structures is evident in the careful retention and adaptive reuse of historically significant buildings on the former hospital site. Deconstructed materials are processed for reuse. In addition to significantly reducing CO₂ emissions, renewable energy sources such as photovoltaic systems and geothermal energy help lower operational emissions.
