With the area being encircled by London, there came to be an economic motive for demolishing some of the existing low-density housing and rebuilding at higher densities for the working class. In 1937 the Church Commissioners built Dibden House containing some 200 flats for social rents at the top of Maida Vale. Following the Second World War there was a great deal of development of large social housing in the constituency. The first large development was John Aird Court and Fleming Court, built by the Labour-controlled Paddington Borough Council adjacent to the Harrow Road by Paddington Green in 1948.
