The "Holzbau Kompakt" series of events organised by the Holzforum Allgäu is an information and qualification platform dedicated to the diverse applications and high performance of wood as a building material on four evenings. On 7 April 2022 (6 p.m.), Prof. Stephan Birk will explain in his lecture "Kreislaufeffektive Bauwende mit Holz" (Cycle-effective building turnaround with wood) how to design and construct renovations, extensions and new buildings so that they can be used as urban mines at the end of a long life cycle.
