Consultants JLL have produced figures indicating that developing car parks for housing could deliver up to 80,000 new homes in the capital.
The research says the prospect of driverless cars and policies for car-free urban areas in London over coming decades - could mean that releasing car parks could provide a solution to the capital’s housing shortage.
The research identified just under 900 car parks in London which could be used for housing, around half of which are owned by local authorities, with 45 in Bromley, 30 in Havering and 27 in Croydon.
The study is an update to a report published earlier in the year, in which JLL found that 350,000-400,000 homes could be developed on car parks in urban areas in the UK.
The report suggested that permitted development rights could be used for car parks under a similar concept as the office-to-residential permitted development rights regime.
Nick Whitten, residential research director at JLL, said London’s population growth had been driven by young professionals choosing to live close to employment hubs and cultural and entertainment quarters.
"However, this trend towards urban living has disproportionately put a strain on London’s local authorities to allocate sites for residential development - typically in areas where land is unavailable", he said. "JLL’s research suggests car parks could provide a solution."
