Nearly 13,000 new homes across west London are set to be fast-tracked after neighbourhoods in Ealing, Harrow and Hounslow became the capital's first 'housing zones'.
Southall, Harrow and Wealdstone town centres and Hounslow town centre are among nine new zones across London which will share a £260 million cash injection.
London mayor Boris Johnson claimed the Greater London Authority funding would 'turbo boost' the transformation of the capital's brownfield sites, creating more affordable homes for hard-working Londoners.
Southall will get 4,345 new homes, 1,785 of which will be affordable, as well as improvements to the station, which will be on the new Crossrail route.
Harrow and Wealdstone town centres comprise the 'Heart of Harrow' housing zone, where more than 5,000 new homes will be built over the next decade.
Hounslow town centre will get just under 3,500 new homes by 2025, including some 750 on the site of the council's current HQ.
A total of 28,000 homes are promised across the nine housing zones, which cover the equivalent of 2,656 football pitches, by the time the status expires in 2025.
Harrow Council's business, planning and regeneration cabinet member Keith Ferry, said the funding would help kick-start the council's 'ambitious' regeneration plans and go someway to addressing the borough's 'chronic' housing shortage.
Ealing Council leader Julian Bell said: "Southall is being transformed through unprecedented investment which will secure its future as one of the premier towns in west London to live, work and visit.
"Getting housing zone status will further stimulate development and ensure thousands of much-needed good quality homes can be built for local people."
Hounslow Council chief Steve Curran said the investment would help address the 'enormous need' for new homes in the borough, where more than 3,000 people are on the council's housing waiting list.
