Summary: We have signed an agreement with Berkeley to deliver 426 new affordable homes at TwelveTrees Park in West Ham, London. We will deliver 148 homes for shared ownership and 278 homes for social rent.
Metropolitan Thames Valley Housing has signed a significant agreement with Berkeley to deliver 426 new affordable homes at TwelveTrees Park in West Ham, London.
As part of the second phase of the development, we will deliver 148 homes for shared ownership and 278 homes for social rent, including 158 three‑bedroom properties to help meet the London Borough of Newham’s urgent need for family housing. Work will begin on site immediately, with all homes due to be delivered by March 2030.
Directly addressing London’s housing shortage, the agreement shows how strong partnership working can help speed up the delivery of new homes. Our acquisition of the 426 homes builds on our long‑standing relationship with Berkeley and has been made possible with support from the GLA’s Affordable Homes Fund, which is helping to deliver thousands of new social and affordable homes across the capital.
Delivered in partnership between Berkeley, GLA Land & Property and the London Borough of Newham, TwelveTrees Park is a 26‑acre regeneration project that will provide more than 4,700 new homes, including 1,650 affordable homes. The development will also include a new bridge into West Ham station, two additional pedestrian bridges, an improved road bridge, a new secondary school for 1,000 pupils, 12 acres of parkland and a £67 million investment in local infrastructure and services through the Section 106 Agreement and Community Infrastructure Levy. Together, these improvements will help transform the area and improve the lives of West Ham residents for generations to come.
Guy Burnett, Executive Director of Development at Metropolitan Thames Valley Housing, said: “Partnership working is essential if we are to tackle the scale of London’s housing shortage, particularly in boroughs such as Newham where demand for family homes continues to grow. Working with Berkeley at TwelveTrees Park will help bring safe, comfortable and affordable homes to West Ham. Available for social rent and shared ownership, these well‑connected Zone 2 homes will offer a fresh start to hundreds of people in housing need.”
Tom Copley, Deputy Mayor for Housing and Residential Development, said: “TwelveTrees Park is a fantastic regeneration project being delivered on City Hall‑owned brownfield land in partnership between Berkeley Homes and the GLA. It will bring high‑quality affordable and social homes right to the heart of east London, alongside new green spaces, improved infrastructure and vital amenities for families and the whole community. The Mayor and I are proud to be supporting this development and look forward to seeing work progress quickly as we continue building a better and fairer city for all.”
Harry Lewis, Divisional Director of Land & Planning at Berkeley, said: “TwelveTrees Park has been built on partnerships, and our continued work with Metropolitan Thames Valley Housing is an important part of ensuring the development provides high‑quality affordable housing in West Ham. Through collaboration, we can help address the demand for well‑designed, affordable homes and create a neighbourhood that will support the local community for generations to come.”
We have worked in partnership with Berkeley Group for more than 25 years, delivering thousands of affordable homes and laying strong foundations for this latest phase of development at TwelveTrees Park.
TwelveTrees Park is a major brownfield regeneration project that will take more than two decades to complete. The former 26‑acre Parcelforce depot is being transformed through a landscaped masterplan by Patel Taylor Architects, featuring a 12‑acre park with water features, gardens and courtyards planted with mature trees.
New amenities including a supermarket, office hub, community centre and science school will help create a thriving new neighbourhood, while the project is expected to create around 500 permanent jobs and more than 8,000 construction roles during the build.
