‘This is an extraordinary group of buildings’, wrote Philip Johnson (then a Mies van der Rohe follower) when The Architectural Review published Alison and Peter Smithson's School at Hunstanton in September 1954. ‘… Here we have an unknown team … being allowed to win and build. Most surprising they are allowed to build not a conventional school, not even a Hertfordshire plan, but something quite the opposite of the prevailing trend … The plan is not only radical but good Mies van der Rohe, yet the architects have never seen Mies's work …’ In this paper, based upon a talk given at the Architectural Association School and on conversations with the Editor, Peter Smithson recalls the background to the project, its design and construction, his later visits to Chicago and a 1973 revisit to the building.
