Pichler worked since the 1960's on the border between sculpture and architecture. First Exhibition 1963 together with Hans Hollein at the Galerie nächst St Stephan in Vienna. Pichler created objects, sculptures and installations - partly mobile - and worked then on architectural design for utopistic visions. 1967 Exhibitions at the Museum of Modern Art New York, Biennale de Paris, 1968 and 1977 Documenta in Kassel.
