Working with a consortium backed by the London Pensions Fund Authority and Grainger will build the homes on a 0.7ha site at Pontoon Dock.

The project, which will see the car parking re-provided, will also improve access to the popular Thames Barrier Park.

The GLA also confirmed it has appointed Galliford Try to deliver more than 1,100 homes at  Silvertown Way in Canning Town, Newham.

The Mayor of London, Boris Johnson, said:  “These two great new developments will turn surplus public land into new homes for Londoners.

“These schemes will be built faster than conventional methods by providing a US-style private rented model alongside traditional tenures.”

The Mayor fast tracked development partners through the London Development Panel, a framework panel of 25 developers.

These sites are among the 670 hectares the GLA took on in 2013, with over 85% already in the pipeline to be developed.

More sites, including Stephenson Street in Newham, will follow later in the year. There have also been recent deals on other GLA owned sites at Cane Hill in Croydon, St Clements Hospital in Tower Hamlets, and Catford Stadium in Lewisham.
