Archigram comprised Warren Chalk (1927-88), Peter Cook (1936-), Dennis Crompton (1935-), David Greene (1937-), Ron Herron (1930-94), and Michael Webb (1937-). Together, in the 1960s and early 1970s, they envisioned the future of architecture in ways that enthralled a generation. In an era defined by the space race, they developed a 'high-tech', lightweight, infra-structural approach that stretched far beyond known technologies or contemporary realities. They devised autonomous dwellings and focused on survival technology; they experimented with mega-structures and modular construction systems; they explored mobility through the environment, and the use of portable living capsules: all through the medium of an incredible series of drawings and models. Archigram's influence has been profound and enduring. They gave the High-tech movement its impetus; they inspired architects such as Renzo Piano and Norman Foster; and they laid the ground for the design of buildings such as the Pompidou Centre. This book catalogues Archigram's activities over fourteen years, together with commentaries by the architects and critics writing then and now. Edited and designed by Archigram member Dennis Crompton, it has been 40 years in the making.
