The London-based architectural group Archigram worked from 1961-1974 on often unbuilt, avant-garde projects that were futurist-pop-constructivist visions of reality and of the built world and that were primarily featured in the group’s magazine. I just learned from the venerable EPCAF (European Post-war and Contemporary Art Forum) about an online archive of their work.
