The Berkeley Group is planning to redevelop the 88-acre brownfield site to build Southall Waterside, which will also include 46,000m2 of commercial space, a two form entry primary school, a health centre and substantial green space.
Work is expected to start on site this year and the scheme will be delivered in a number of phases over a 25 year period.
The revised masterplan will see more than half the site set aside for open space, including landscaped public parkland, leisure and play spaces, and piazzas.
Berkeley is now preparing a detailed planning application for Phase A of the development. This is expected to include 618 new homes in the northeast corner of the scheme, of which 186 are designated affordable. It also features roads, parking, landscaping and access to public realm.
Subject to approvals, first completions for Phase A are anticipated for mid-2018.
Berkeley Group executive director Sean Ellis said: “These gasworks closed almost 50 years ago, so approval of the Southall Waterside masterplan marks the start of an exciting new future for this 88 acre site. It is the largest regeneration scheme in West London. It creates a much more diverse residential and commercial offer for Southall. And when 80% of new homes currently planned for the capital are in just three East London boroughs, this provides some welcome balance.”
