Developer Mount Anvil and housing association Peabody are behind the 1,345-home regeneration, which will now move into its last stage with another 693 homes set to be built.
The full scheme replaces the old Friary Park estate with a mix of private and affordable flats, improved public space and a raft of community facilities.
Around 470 of the new homes will be affordable, and all existing tenants have been offered the chance to move into a new place on site.
The third and final phase was designed by HTA Design and will help meet nearly a third of Ealing’s annual housing target..
Friary Park is one of several major projects in the pipeline for the Mount Anvil/Peabody JV – including the 266-home rebuild of Watermeadow Court, 307 homes at One Clapham, and the 327-home Three Waters scheme in Bromley-by-Bow.
