One of three estates designed by Joseph Emberton in Ec1, the Brunswick Estate dates from the mid-50s.
According to Catherine Moriarty and Sue Breakell at Archives Hub:
“Emberton (1889-1956) was one of Britain’s most significant architects during the inter-war period. His projects introduced modern design to broad audiences, among the best known being the Royal Corinthian Yacht Club at Burnham-on-Crouch (1931), Simpsons of Piccadilly (1936) and Blackpool Pleasure Beach (1935-9).
“After the Second World War, Emberton”s focus in a period of austerity shifted to social housing. His prototype steel house was designed for the Ministry of Works, where he was a consultant, a radical project for prefabricated housing which was thwarted by steel shortages. There followed a series of flats, commissioned by the London Borough of Finsbury, Stuart Mill House, the Stafford Cripps Estate and the Brunswick Estate (1953-1958).”

Great post. The flats at the Brunswick centre in Bloomsbury is one of my favourite buildings in London.
I like the Brunswick Centre, in WC1, as well and lived near there for a bit. The Brunswick Estate in EC1 is comprised of Brunswick Court, Emberton Court and Wyclif Court.
Never been, might go and look, thanks for introducing me to it.
