The KIT Future Fields stage 2 project "Willow Weave" contributes to the strategic development of the promising and socially highly relevant research field Digital Circular Construction as a Future Field at KIT. The pilot project enables networking preliminary work through the holistic experimental research of an exemplary structural component made of willow-clay composite on a 1:1 scale and promotes coordinated innovations in the fields of digital construction, sustainable construction, construction design, structural engineering, component testing, and life cycle assessment within the framework of an integrative co-design process.
