Under the development agreement, 35% of the new homes at Beam Park will be mixed-tenure, with a significant proportion of shared ownership properties marketed to the local community first.
A new railway station on the C2C line, a primary school, swimming pool and other community facilities are also proposed.
Countryside and L&Q were selected from a shortlist of four developers as part of the London Development Panel procurement process, which was set up by the Mayor of London to accelerate the delivery of housing in the capital.
Construction is expected to begin in 2017. Countryside’s Partnerships division will build all of the private and affordable homes on the development.
Richard Cherry, CEO of Partnerships at Countryside said: “Countryside is delighted to have been selected for this hugely important new scheme which will spearhead the regeneration of the London Riverside Opportunity Area.”
Jerome Geoghegan, Group Director, Development and Sales at L&Q said: “Housing supply is the critical issue affecting the growth of London and the quality of life enjoyed by Londoners, so we are very excited to have been selected by the GLA as a delivery partner on such an important strategic site as Beam Park where we can do so much to meet that need.
“L&Q is aiming to build 50,000 new homes over the next decade and we plan to reach that goal by creating quality homes in places where people want to live.”
The Mayor of London, Boris Johnson said: “This impressive site is now set to be transformed into a thriving new neighbourhood. As well as much needed new homes of every tenure, the brand new station will whisk residents into central London in record time, and the development will include mass green public space along the River Beam.”
