Gianni Pettena , along with Archizoom, Superstudio and Ufo,  belongs to the original nucleus of the Italian radical architecture movement. Since the Seventies, his work and theoretical and experimental propositions, expressed in the form of design projects, interior design, architecture, museum installations and performances, has conversed and merged with the evolution of the world of the arts in a continuum of comparisons and participation in exhibits in museums and galleries. The languages of ‘spatial’ art, of conceptual art and of American land art, acquired and experimented in the United States through his many artist friends, are assimilated and implemented over the following years, also through his work as professor and critic.
