A postwar review of inadequate housing led to the clearance and redevelopment of areas of the city in a postwar style, often at variance with the local Georgian style. In the 1950s the nearby villages of Combe Down, Twerton and Weston were incorporated into the city to enable the development of housing, much of it council housing. In 1965 town planner Professor Colin Buchanan published "Bath: A Planning and Transport Study", which to a large degree sought to better accommodate the motor car, including the idea of a traffic tunnel underneath the centre of Bath. Though criticised by conservationists, some parts of the plan were implemented.
