Frustrated, Lubetkin spent increasing time at the Gloucestershire farm he had managed for Beamish family since the start of World War II, before purchasing it for himself. Though he failed to win several design competitions during the 1950s, he (again with Bailey and Skinner) designed three large council estates in London's Bethnal Green (now a part of Tower Hamlets). These schemes, the Cranbrook Estate, Dorset Estate (which featured the tower Sivill House) and the Lakeview Estate all made increased use of precast concrete façade panels while developing the idiom of complicated abstract facades and Constructivist staircases established in the 1940s.
