Site constraints 6

Gunnersbury Park conservation area
Also Gunnersbury Park (article 4). Demolition needs planning permission and permitted development is restricted.
The council must give weight to preserving or enhancing the area's character and appearance. Not every council has published its boundaries as open data.
2 Article 4 directions
Dwellinghouses (C3) to small HMOs (C4) - borough-wide Article 4 Direction · Article 4(2) directions for Bedford Park and Gunnersbury Conservation areas. Named permitted development rights are withdrawn here.
An Article 4 direction withdraws particular permitted development rights, so work that would normally need no application needs one here. Not every council has published its directions.
Heritage at risk: Gunnersbury Park, Brentford
On the register of historic places assessed as at risk.
A designated building, monument, park or conservation area assessed as at risk from neglect, decay or development. Proposals that secure its future are looked on favourably.
Historic England ↗
Air quality management area: Hounslow AQMA
The council has declared the area as failing an air quality objective.
Schemes that add traffic, parking or combustion plant are assessed against the area's action plan and may need an air quality assessment.
Council record ↗
Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Also on the record
Inside the Hounslow built-up area.
Not affected
Outside flood zones 2 and 3 · Not green belt · No listed building at the site

Checked on 24 September 2026. Historic England, the Environment Agency, Natural England and council datasets, Open Government Licence. A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
