Archigram

"When the practise dissolved in 1974, Archigram had realised three projects, all completed in 1973 by Dennis Crompton and Ron Herron: a children’s playground in Milton Keynes, an exhibition at the Commonwealth Institute in London and a swimming pool for the singer Rod Stewart. 'Archigram gave us a chance to let rip and show what we wanted to do if only anyone would let us,' said Ron Herron just before his death in 1994. 'They didn’t.'"
