The Hounslow Planning Committee met to discuss several planning applications, including a large mixed-use development at the Sega Site on the Great West Road, and the redevelopment of Griffin Park, the former Brentford Football Club stadium. The committee approved the Sega Site development, after adding a condition to reduce parking provision, and also approved the Griffin Park redevelopment.

Major Planning Decisions

Sega Site Redevelopment (27 - 1053 Great West Road)

The committee approved the application for the redevelopment of the Sega Site, also known as 27 - 1053 Great West Road, subject to conditions and the completion of Section 106 and 278 agreements¹. The plan includes demolishing existing buildings and constructing a mixed-use development featuring 856 homes, commercial and retail spaces, highway and public realm improvements, landscaping, and parking facilities.

Arguments for approval included the optimisation of an underused brownfield site within the Great West Corridor Opportunity Area, the provision of 266 affordable homes (31% of the total), and a design that enhances the area while minimising harm to nearby heritage assets. The development aims for a minimum 67% reduction in emissions, aligning with sustainability goals.

Objectors raised concerns about harm to heritage assets, insufficient affordable housing, strain on local infrastructure, and potential air quality and noise issues. Despite these objections, the committee found the public benefits outweighed the potential harms.

Griffin Park Redevelopment, Brentford

The committee approved the application for the redevelopment of Griffin Park, the former Brentford Football Club stadium, to provide 149 residential units, subject to conditions and a Section 106 agreement. The development includes 41 houses, a four-storey apartment block, and two six-storey apartment blocks, along with landscaping, parking, and other associated works.

The decision was made despite objections from residents regarding the number of dwellings, design concerns, loss of light and privacy, increased traffic, and the impact on local services. Supporters of the scheme emphasised the need for more family homes and the benefits of the central park.

The committee considered the scheme to be of high design quality, suited to the site and surroundings, and providing a high standard of residential accommodation. The development is expected to achieve a 65% carbon dioxide emissions reduction and a Biodiversity Net Gain of +55.71%.

Other Business

Rivers Academy Applications

The committee also considered two applications relating to Rivers Academy: one for the erection of a three-storey school building and a sports block (P2025/1058), and another for a temporary school building and playing fields (P2025/1059). Both applications were approved unanimously.

10 Almorah Road, Hounslow

The committee approved a certificate of lawfulness for a proposed rear roof extension at 10 Almorah Road.

Declarations of Interest

Councillor Tom Bruce, Cabinet Member for Planning and Regeneration, declared that he had received emails regarding items 4, 5, 6 and 7. Regarding item 4, he had met the applicant with officers present to receive information, but his views had not been discussed, and he remained open-minded about the application.

All members present advised that they had received emails regarding items 4, 5 and 6.

Councillor Adesh Farmahan advised that he had a family member who currently attended Rivers Academy.

Councillor John Todd stated that he was a Trustee of Chiswick House Trust.

Gunnersbury Park Music Event

During a discussion about a proposed music event in Gunnersbury Park, Councillor Joanna Biddolph, who lives in Gunnersbury ward, raised concerns about noise levels, anti-social behaviour, and the impact on local businesses and residents. She described a previous event as causing doors to rattle alarmingly, pictures on walls clattered, sofas shook and a torrent of people filled the pavement. She also criticised the Gunnersbury Estate (2026) CIC for being unelected, undemocratic and unaccountable.

Siyka Doneva raised concerns about predetermination, noise levels exceeding WHO guidelines, drug use, and harm to protected animals. She claimed that the park was booked for 98 days of commercial events in 2025, exceeding the legal limit.

David Bowler, CEO of Gunnersbury Estate (2026) CIC, Tom Paine, Waterworks Event Organiser, and Chris Piris-Jones, Planning Consultant, spoke in favour of the application, stating that 100% of the income generated by the charity was reinvested into the park. They also noted that the police were happy for the event to be self-policed by stewards.

Councillor Tom Bruce objected to claims of conflict of interest and predetermination, and legal adviser Michael Jones confirmed that if the committee refused the application, the organisers would be obliged to refund everyone who had prebooked.

Despite the concerns raised, the committee voted to approve the application unanimously.
