Site constraints 15

Grade II listed: Morton House Railings of Morton House
List entry 1079589 · 1 m away · 15 more listed buildings within 150 m (1 Grade I, 2 Grade II*, 12 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.
Show the other 15 with distances
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 ↗
Old Chiswick conservation area
Also Old Chiswick. 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.
Article 4 direction
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 Named permitted development rights are withdrawn here.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.
National infrastructure project: Thames Tideway Tunnel
The site is inside the project boundary. Waste water treatment, decided. The project page says whether consent was granted.
Nationally significant infrastructure projects (power stations, electricity lines, pipelines, major roads and railways, harbours, airports and reservoirs) are consented by a Secretary of State under the Planning Act 2008, after an examination by the Planning Inspectorate, rather than by the council. The boundary is the one the Inspectorate consults on and can change as the scheme does. Projects are shown within 2 km of the site.
Planning Inspectorate project page ↗
Local nature reserve 64 m away: Chiswick Eyot
Work nearby can need a habitats assessment.
Harm to a protected site is only accepted where there is no alternative and an overriding public interest.
Archaeological priority area: A riverside village with Saxon origins.
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 ↗
Thames Path 13 m away
Matters where it crosses or adjoins the site; the route and its margin are protected.
Registered park or garden 2 m away: Strawberry House
Its setting is a consideration for work nearby.
Registered parks and gardens, battlefields, world heritage sites and protected wrecks are designated heritage assets: harm needs clear and convincing justification.
Historic England ↗
Also on the record
Flood defence 3 m away (flood gate); Inside the Hounslow built-up area; Public transport access: PTAL 2 (poor), TfL 2023, for the 100 m square; Metropolitan Open Land 27 m away; Priority habitat 28 m away: Mudflats.
Not affected
Not green belt · No scheduled monument at the site
