The Isokon building on Lawn Road, Hampstead, London, is a concrete block of 34 flats designed by architect Wells Coates for Molly and Jack Pritchard. They opened on 9 July 1934 as an experiment in minimalist urban living. Most of the flats had very small kitchens as there was a large communal kitchen for the preparation of meals, connected to the residential floors via a dumb waiter.
