Peabody has been granted planning permission for a 564-home development in west London.
The 67,000-home housing association has been given the go-ahead for The Green project in Southall, which it is developing as part of a partnership agreement with Ealing council.
The project, which will be designed by architects Hunters, includes 564 homes in three blocks. Around 50% of the homes will be for affordable tenures.
The homes have been described by Peabody as low carbon with the development achieving an overall reduction in CO2 emissions of at least 65.33%, according to planning papers.
Heating will be provided through a communal site-wide heat distribution network via a ground source heat pump while photovoltaic panels with a combined capacity of at 237kwp will be installed.
The development will also include new public spaces.
Meanwhile, the firm has submitted an outline planning application for a 3,500 home mixed-use development on the site of a former car factory in Dagenham.
The planned development on the site of an old Ford stamping plant in the Essex town will be designed by PRP Architects, with HTA Design working on the landscape and public realm.
Peabody is planning to merge with fellow G15 housing association Catalyst next April to create a 104,000-home association.
New chief executive Ian McDermott said the move will enable the enlarged group to maintain their joint 3,000 homes a year pipeline in the face of issues such as building safety, decarbonisation costs and inflation.
