A plan to sell 15% of state-owned car parks could free up land for 110,000 homes.

In a review commissioned by the Ministry of Housing, Communities and Local Government Knight Frank’s head of geospatial research, Ian McGuinness, has identified 4,700 car parks which could be suitable for development.

In the Greater London area (including adjoining built-up areas such as Watford) 759 car parks could be turned into 14,915 homes. In Greater Manchester and adjoining areas, meanwhile, there are 144 car parks that could be turned into 4,687 homes.
