Ealing Council planners have backed plans for 215 mixed-tenure homes at the former South Acton estate.
With planning approval now granted for Phases 9.3, 9.5 and 9.6 of Acton Gardens, works are expected to begin in July.
The site completes the Enfield Road Character Area, which serves as a gateway to Acton Gardens from Acton Town station and Bollo Lane.
Acton Gardens is a 52-acre largescale redevelopment of the former South Acton estate – an £800m investment creating nearly 3,500 new mixed-tenure homes.
The development delivers 50% affordable housing and more social rent homes than previously existed on the estate before the project commenced.
