The Weißenhofsiedlung on Stuttgart’s Killesberg, built within a few months in 1927, was tantamount to a revolution in building: the designs of various world-famous architects showed how we could build and live in the future.

Parts of the Weißenhofsiedlung were destroyed during the war and rebuilt – except for a plot of land in Bruckmannweg, which has lain fallow since 1945. Here, for a period of five years, stood an equally future-oriented building that demonstrated how innovative materials, constructions and technologies can sustainably improve our built environment.

Modular, Forward-Looking, Neighbourhood-Oriented

B10 Werner Sobek Sustainability

The research project – called “B10” for short after its location at Bruckmannweg 10 – is the world’s first active house. Thanks to a sophisticated energy concept and a self-learning building control system, it generates twice its energy needs itself. And it does so from sustainable sources.

In August 2019, the experimental building was lifted by crane onto a heavy transporter within one day and reassembled at its production site in Hohenstein-Oberstetten.
