Preferred bidder Triangle London Developments will now form a joint venture with TfL to develop the 4-acre vacant site in Kidbrooke with new homes, commercial, retail and office space.

It sits to the north of Kidbrooke station on the opposite side of the tracks to Berkeley Homes’ development.

Triangle London Developments is a joint venture between developer U + I and the Notting Hill housing association’s home ownership business.

The partners will now develop concept designs in order to seek planning permissions and start on site in 2018, aiming to have the first homes available to buy and rent by 2020.

Kidbrooke was the first in a series of TfL sites to be released for development last year to support the Mayor of London’s manifesto pledge to unlock public land to build thousands of affordable homes for Londoners.

Other sites include Landmark Court in Southwark, which has the potential to deliver a mixed-use scheme with 35 per cent affordable housing, and Fenwick South in Lambeth, which will provide 55 homes, which will all be social housing.

James Murray, Deputy Mayor for Housing and Residential Development, said: “Kidbrooke is a site that has sat unused for the last eight years, so I welcome this joint venture and I look forward to seeing work gather pace to deliver new affordable homes for Londoners to buy and rent.”

Graeme Craig, TfL commercial development director, said: “This is the first of dozens of sites across London that we expect to bring forward in joint venture using our Property Partnerships Framework, and it is a great place to start.”
