text: Archigram Archigram was an avant-garde architectural group formed in the 1960s - based at the Architectural Association, London - that was neofuturistic, anti-heroic and pro-consumerist, drawing inspiration from technology in order to create a new reality that was solely expressed through hypothetical projects. The main members of the group were Peter Cook, Warren Chalk, Ron Herron, Dennis Crompton, Michael Webb and David Greene. Designer Theo Crosby was the "hidden hand" behind the group. He gave them coverage in "Architectural Design" magazine (where he was an editor from 1953–62), brought them to the attention of the Institute of Contemporary Arts (ICA) in London, where, in 1963, they mounted an exhibition called "Living Cities", and in 1964 brought them into the Taylor Woodrow Design Group, which he headed, to take on experimental projects. The pamphlet "Archigram I" was printed in 1961 to proclaim their ideas. Committed to a 'high tech', light weight, infra-structural approach that was focused towards survival technology, the group experimented with modular technology, mobility through the environment, space capsules and mass-consumer imagery. Their works offered a seductive vision of a glamorous future machine age; however, social and environmental issues were left unaddressed.
