FREI OTTO 100

The Spirit of Lightweight Construction

Frei Otto (1925-2015) was a visionary innovative architect and master of lightweight structures. May 31, 2025 marks the 100th anniversary of his birth. To commemorate his exceptional spirit of experimentation, his works, methods, and international networks, the University of Stuttgart organizes a two-day convention.

Frei Otto 100 | The Spirit of Lightweight Construction will take place at the Institute for Lightweight Structures and Conceptual Design (ILEK) in Stuttgart-Vaihingen, formerly known as IL (Institut für Leichte Flächentragwerke). Its tent structure, designed by Frei Otto as a prototype for the German Pavilion at the EXPO ‘67 in Montreal, provides an inspiring space for open reflection on past and present achievements in the field of lightweight construction.

The two-day event will include a historical reflection on Frei Otto’s work, methods and networks, supported by the testimonies of several contemporary witnesses. It will also focus on how different generations of researchers and practitioners interpret the legacy of the Stuttgart School of Lightweight Construction.
