Radical architecture
Term used (1960s, 1970s) to suggest extremes of shape, structure, or (more usually) the Leftist political position of its creators, propounded largely by the journal Casabella. In reality Radical architecture was often drawn or collage presentation of projects by certain groups (e.g. Archizoom), usually involving assaults on architecture conceived as a formal language.
