At the end of the 20th century, Werner Sobek designed his four-story R128 residential building as a completely recyclable zero-heat energy building that is emission-free in operation. The special feature of this house on the edge of the Stuttgart basin: It has a modular design and, thanks to its plug-and-screw assembly, is not only easy to erect and dismantle, but can also be recycled into the resource cycle.
High-quality triple glazing, together with a climate control concept specially developed for R128, ensures that as little energy as possible is lost in winter – and that only a fraction of the heat reaches the interior in summer. In the video interview, Werner Sobek now looks back and explains how R128 came about – from the idea to the concept to the construction. A fascinating look behind the scenes of one of the most publicized single-family houses of recent decades.
