Housebuilder Countryside is to help create more than 900 homes in east London.
The Essex firm has partnered with housing association Notting Hill Housing to build the homes for sale and private rent at Fresh Wharf in Barking town centre.
The scheme will create a total of 911 units, from three-bedroom townhouses to 15-storey apartment buildings.
Work on site will start in 2018 and is scheduled to take around eight years.
Notting Hill Housing subsidiary Folio London has agreed to acquire 157 PRS homes from the joint venture.
Countryside Partnerships South chief executive Graham Cherry said: “This is an exciting new development in an increasingly popular London location.
“The site is identified as one of the largest residential sites within the Barking Town Centre Area Action Plan, which makes a significant contribution towards the council’s target of some 6,000 new homes.
“We are looking forward to revitalising this area with our partner, Notting Hill Housing, and building much-needed new homes for London.”
Transport for London is extending the London Overground Gospel Oak to Barking line to aid the development of more than 10,000 homes at Barking Riverside, as well as a school, healthcare and retail facilities.
Balfour Beatty, Carillion and VolkerFitzpatrick were shortlisted for the extension project last year.
