Site constraints 12

Grade II listed: Crown and Anchor Public House
List entry 1079584 · 9 m away · 5 more listed buildings within 150 m (1 Grade II*, 4 Grade II)
Listed building consent is needed for work that affects the special interest of a listed building, inside or out, on top of planning permission. Setting can be a consideration for buildings nearby; there is no fixed radius.

Historic England ↗
Flood zone 3, rivers and sea
High chance: a 1 in 100 or greater annual chance from rivers, or 1 in 200 from the sea. Any development here needs a flood risk assessment. Defences are not counted.
The Environment Agency flood map for planning. Homes in zone 3 must also pass the sequential test. Surface water flooding is a separate map.
Flood map ↗
Turnham Green conservation area
Also Turnham Green. 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
Change of use or development that would result in new dwellings (Class MA/ZA) · Dwellinghouses (C3) to small HMOs (C4) - borough-wide Article 4 Direction. Named permitted development rights are withdrawn here.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.
Archaeological priority area
An assessment or field evaluation may be asked for before ground works.
The council or Historic England considers archaeology likely here. A desk-based assessment, and sometimes trial trenching, can be asked for with the application.
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 ↗
Town centre: Chiswick
A designated centre in the London Plan.
Shops, services and active frontages are protected in centres, and main town centre uses are steered here first.
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
Local nature reserve 346 m away: Gunnersbury Triangle; Inside the Hounslow built-up area; Designated open space 36 m away; Open access land 41 m away: Access Land - Combined Open Country, Registered Common Land and Section 16 Dedicated Land. MoD Byelaw, Section 28 Exclusions, Racecourses and Aerodromes and ECP Margin have been removed..
