The name of the group (six-strong, for much of its formal existence from 1961 to 1974) overshadows its constituent members. Unless you inhabit the world of architectural academia, you will most likely not have heard of Cook, nor of Warren Chalk, Dennis Crompton, Ron Herron, David Greene or Michael "Spider" Webb. Herron eventually developed a bit of a public profile later in life as a commercial architect, then died. And it was Herron, author of several of the best Archigram projects including Walking City, who best summed it all up, just before his death in 1994. "Archigram gave us the chance to let rip and show what we wanted to do if only anyone would let us," he said, adding: "They didn't."

Things got exciting in 1969, when Archigram won a competition for a leisure centre in Monte Carlo, and set up as a real architecture studio. But the centre was never built. In fact, Archigram only ever built three things under its own name, all designed by Crompton and Herron in 1973: a children's playground in Milton Keynes, an exhibition at the Commonwealth Institute, and a swimming pool for Rod Stewart. Which only goes to show that you can get very famous in architecture for reasons other than building.
