Prior to bombing during World War II, the adjacent boroughs of Stepney and Poplar, in London's East End, had suffered from urban blight in the forms of overcrowding, obsolescent buildings and lack of open space. 2000 acres were designated as a Comprehensive Development Area no 2 by London County Council. This was replanned as a series of eleven neighbourhoods in 1948-1949. Residential density was set at 136 persons per acre, for a planned population of 100,000 in total. Each neighbourhood had its own community, educational and shopping facilities. Industry was zoned along the canal and by the docks, a new road pattern established and large new public open spaces laid out. Neighbourhoods included Lansbury, which featured in the "Live Architecture" Exhibition, as part of the Festival of Britain in 1951, and the completely new neighbourhood of St Anne's, at Limehouse.
