Isokon's key project was the Lawn Road Flats in
Hampstead, called the Isokon building since 1972, which was formally opened on 9 July 1934. It was designed by
Wells Coates after a brief by Molly Pritchard, based on the Minimum Flat concept presented at the
CIAM (Congrès internationaux d'architecture moderne) conference of 1929. In March 1931,
Wells Coates,
Jack Pritchard and
Serge Chermayeff had visited Germany, including the
Bauhaus school and the Törten Estate in
Dessau, both designed by
Walter Gropius, which possibly influenced the design of Lawn Road Flats. The building process and the opening event was photographed by
Edith Tudor-Hart (née Edith Suschitzky) who was educated 1928–30 at the
Bauhaus school in
Dessau, but also a recruiter for Soviet intelligence. Intended to be the last word in contemporary living, the block of flats was aimed at young professionals. It contained 22 single flats, four double flats, three studio flats, staff quarters, kitchens and a large garage. Services included shoe cleaning, laundry, bed making and food sent up by a dumb waiter at the spine of the building. In 1937, a restaurant and bar designed by
Marcel Breuer and
F. R. S. Yorke named the Isobar, located on the ground floor with a decked outdoor area, was added to the building. Its second manager was
Philip Harben, who after World War II became the first TV chef at the BBC.
Jack Pritchard also set up a supper club called The Half Hundred Club, so named because it could have no more than 25 members who could bring 25 guests. They dined at the Isobar, at Pritchard's penthouse flat in Lawn Road Flats or at more exotic locations, such as
London Zoo. The flats and the Isobar became famous as a centre for intellectual life in north London. Residents included the novelist
Agatha Christie and her husband, the archaeologist
Max Mallowan, the Soviet intelligence recruiter
Arnold Deutsch who was the controller of the group of Cambridge educated Soviet spies who came to be known as the
Cambridge Spy Ring, the German born economist and Communist
Jürgen Kuczynski, the author
Nicholas Monsarrat, ethnomusicologist
Erich Moritz von Hornbostel, architect
Jacques Groag and his textile designer wife
Jacqueline Groag, architects Egon Riss and
Arthur Korn and the author
Adrian Stokes. The British architects
Sir James Stirling and Alec Bright, later director of the
Museo del Oro in Bogotá, Colombia were resident during the 1960s. Regulars at the Isobar included the sculptors
Henry Moore and
Barbara Hepworth, the painter
Ben Nicholson and
Naum Gabo, all who lived locally, as well as
Sir Julian Huxley, secretary of the
Zoological Society of London 1935–1942. Pritchard remained in London during World War II while Molly Pritchard and their children Jonathan and Jeremy left for America where the children were put in a boarding school in Canada while Molly moved in with Walter and Ise Gropius in Lincoln, Massachusetts. Lawn Road Flats was popular as a residence during the war due to being made out of reinforced concrete, and despite near bombs, survived the Blitz. It was repainted brown during the war as it was feared its white surface would serve as a navigation aid for German bombers. In 1955, Pritchard staged a 21st-birthday party for the building on its roof top terrace.
Philip Harben returned to make the food, architectural writer
Nikolaus Pevsner made a speech and letters from
Walter Gropius,
Marcel Breuer and
Agatha Christie were read out.
Wells Coates as well as many pre-World War II residents attended the event. From 1966, Jack and Molly Pritchard increasingly spent their time at a new home in
Blythburgh, Suffolk, designed by Jack's daughter Jennifer Jones (née Tudor-Hart) and her husband Colin, although they kept the penthouse at Lawn Road Flats until the mid 1970s. The modern bungalow, also called Isokon, is still owned by the Pritchard family. Pritchard sold Lawn Road Flats in 1969 to the magazine
New Statesman, who demolished the Isobar and converted it into flats. They then sold the building to
Camden Council in 1972 for twice the price. The building was listed Grade II in 1974 by
English Heritage and listed Grade I in 1999. Despite this, it received poor maintenance from Camden Council and deteriorated badly. During this period, it was chiefly used to house single men with drug, alcohol and mental health problems. After a long campaign to save the building, it was sold to the housing association
Notting Hill Housing Group in 2003, in a joint bid with
Avanti Architects, headed up by architect John Allan, with the pledge that a museum would open in the building. It now contains 36 flats, most that are owned on
Equity sharing basis by key workers such as nurses and teachers. In July 2014, the building's garage was converted into a permanent exhibition that tells the story of the building, its residents and the Isokon company. It is operated by the not-for-profit charitable Isokon Gallery Trust and is open 11 am to 4 pm each Saturday and Sunday from early March until the end of October every year. ==Bauhaus in Britain==
