Hungarian-born, he moved to Paris in 1957, and made his reputation as an architectural theorist and visionary designer. With Frei Otto and others he founded the Groupe d'Étude d'Architecture Mobile (GEAM—Group for the Study of Mobile Architecture), and evolved the notion of the city as a primary permanent infrastructure or framework with a changeable impermanent secondary structure determined by the users and erected using simple technologies. He published several books expounding his ideas, including L'Architecture Mobile (1970) and Alternatives Énergétiques (1980). He has been considered as contributing to Experimental architecture, and is associated with Megastructures and Mobile architecture.
