Ealing Council is leading plans for a major new regional park that could transform a 500-hectare corridor of green space and waterways stretching from Horsenden Hill to the River Thames.
The proposed West London Regional Park, formally launched at Osterley House on Monday (2 March 2026), brings together Ealing Council with Hounslow Council, the Mayor of London, the National Trust, the Environment Agency and the Canal & River Trust. The partners say the scheme could ultimately benefit up to two million Londoners by improving access to nature, restoring habitats and creating new routes for walking and cycling.
At the heart of the emerging vision is a connected landscape running from Horsenden Hill in Greenford, through Osterley Park and Hounslow, to Brentford and the Thames. Early proposals include a 13km walking and cycling trail linking parks, waterways, landmarks and public art, alongside new sports and wellbeing spaces, improved signage and access, enhanced wildlife habitats and outdoor venues for cultural events.
The project is backed by almost £2.5m in initial funding. City Hall has pledged almost £1.5m to help kick-start delivery, while Ealing Council secured a £999,595 grant from The National Lottery Heritage Fund last summer through its Nature Towns and Cities programme to develop plans, including work on how expanded green space could support residents’ health.
Peter Mason, leader of Ealing Council, said: “What began as a simple but powerful idea by Ealing Council to connect our green spaces into a regional park for our residents has grown into something far larger than any one borough. By joining forces with our neighbours and partners, we now have a shared ambition to create a truly transformative West London Regional Park for millions to enjoy.”
Speaking at the launch, Brent River Park Charity chair Katie Boyles said: “Our Brent River and Canal Society was formed over 50 years ago by Luke FitzHerbert, who successfully campaigned for the creation of the Brent River Park – a 7km string of green spaces that follow the River Brent, bringing walking routes, connecting communities and creating healthy wildlife corridors. It was designed as a Regional Park and has been enjoyed by generations since its opening in 1975.
“Yet it’s important to remember that the complete extent of Luke’s Brent River Park ambition was never fully realised. It was always part of our founder’s vision to extend the park into neighbouring boroughs and to link it with other green spaces such as Osterley Park and Horsenden Hill. The Regional Park presents an opportunity to realise some of that vision – making the Brent River Park bigger, connecting and creating new open green spaces, with accessible walking routes, bringing people and nature together all the way down to the Thames. It also gives us a renewed impetus to ‘Clean Up the River Brent’ that will lie at the heart of the park. Being mindful of the responsibility and care this project must carry, we welcome the opportunity to continue Luke’s legacy and leave an enhanced rewilded and healthy park for future generations.”
Mete Coban, the deputy mayor for environment and energy, said the investment was intended to help more Londoners reach “green and blue spaces” close to home, adding: “Every Londoner should be able to access green and blue spaces and benefit from nature.”
The partnership will now map existing assets, identify opportunities for habitat creation and nature recovery, and consult residents, businesses and community groups as it develops a long-term strategy. Organisers said early improvements could be delivered on the ground while the wider plan is drawn up, with further updates and opportunities to get involved expected throughout 2026.
