On November 12, 2025, the Collection Network visited the Institute for Lightweight Design and Construction (ILEK). Founded by Frei Otto as the Institute for Lightweight Construction, it houses a collection of specialized literature and documents on lightweight construction, as well as numerous models. Using these resources, the institute continues to explore key questions in lightweight construction technology to the present day—from soap films and steel nets to lightweight concrete and adaptive shells.
Many thanks to Ms. Theresia Ludwig, M.A., for the fascinating insight into the collection, and to Prof. Lucio Blandini for presenting the new areas of research at the Institute for Lightweight Design and Engineering.
