Notting Hill Housing has secured planning permission for up to 940 new homes to be built on the site of Hounslow Civic Centre.
The plans, given the green light last week, will also see a new, smaller, civic centre created nearby, which will include a library and café.
At least 40 per cent of the homes will be affordable, and work is set to begin on both sites this summer.
There will be a mixture of studio, one, two and three bedroom homes on the Lampton Road site, with building varying between three and nine storeys.
The first 160 homes are set to be completed in spring 2018 with the rest, up to 780, expected to be finished in 2022.
Notting Hill Housing and Bouygues Development were appointed by Hounslow Council last summer to develop these projects, which have been boosted by a £15m Housing Zone grant from the Mayor of London.
John Hughes, Group Development Director for Notting Hill Housing, said: “This is one of the most exciting projects we have ever undertaken, as well as one of the biggest. The new development will deliver desperately-needed new homes, both private and affordable, in a fantastic park-side location.
“Working in close collaboration with Hounslow and the GLA to deliver our shared vision of a new high-quality integrated community, we are confident this new landmark development will be a great success.”
