Bildung, Betreuung, Begegnung (Education, care, encounters)

Education, care and encounters viewed as a triad of lifelong learning: in this spirit, an exemplary project for the knowledge-based society was developed in Bahnstadt from 2012 to 2017.

»A sustainable city of knowledge needs places where lifelong learning and exchange between different environments can take place and identity is created. B3 will be such a place for the new district Bahnstadt.«

IBA advisory board

A day care center, a primary school including a sports hall, and a community center were designed as one building with high architectural and content-related standards, thus creating the structural conditions for cooperation and a new coexistence. 

The day-care center and the school facilitate a variety of encounters. The community center, run by the district association, offers activities for all ages, and encourages lifelong learning and cultural exchange. The innovative building ensemble also creates an prominent meeting place. The architect Peter Donn from Stuttgart won the competition for the realization of his first school building in 2012. The landscape architecture of KUULA from Berlin completes the picture of the courtyards and the Gadamerplatz in front of them. The building has a uniform appearance although it consists of four independent building units for the planned uses: The almost 10,000 square meter building complex combines a three-class primary school with sports hall, a daycare facilities for four groups of children, a community center with a public café, multi-purpose rooms and a community hall. The buildings are connected in many ways and are grouped around an inner courtyard, which is open to the public in the afternoon.
