[1] An active member of late 1930s Modernist circles, he was a British delegate to the International Congress of Modern Architecture (CIAM).
In 1936, Tatton Brown, his wife Aileen, and Hubert de Cronin Hastings (Architectural Press proprietor) formed a three-strong 'Town Planning Committee' within CIAM exploring ideas related to 'linear cities'; Tatton Brown subsequently presented a paper based on the work, The Theory of Contacts and its Application to the Future of London, at the CIAM V Congress in Paris in September 1937.
[4] However, this work was subsequently regarded as a "a preliminary survey of London by a section of the MARS Group", and a new and larger Town Planning Committee was convened under Arthur Korn's leadership in December 1937 to produce a revised plan for London under the auspices of the MARS Group which exhibited the initial city ideas at its New Burlington Galleries exhibition in 1938.
[1] Despite severe post-war materials shortages, he led a team of talented architects including David and Mary Medd to deliver prefabricated buildings combining lightweight structures, panels and tubular steel trusses.
[6] Despite officially retiring in 1971, he continued to work for several years, and in 1985, a book he co-wrote with Paul James, Hospitals: Design and Development, was published.
