Site constraints 14

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 Named permitted development rights are withdrawn here.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.

In flood zones plus climate change

Inside the extent flood zones 2 and 3 could reach with climate change: the Central allowance for the 2080s on rivers, the Upper End allowance for sea level rise to 2125. From the sea. Defences are not counted.

The Environment Agency flood map for planning. Councils use it to decide when a flood risk assessment and the sequential test are needed. It is indicative and does not show whether a particular property will flood.

Flood map ↗

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 ↗

National infrastructure project 343 m away: Thames Tideway Tunnel

The site is 343 m from 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 ↗

Habitat network: Network Enhancement Zone 2

Where habitat is joined up enough to work as a network. Context, not a constraint on its own.

5 listed buildings within 150 m

Nearest: Cross of Sacrifice, Grade II, 55 m away · 5 Grade II

The site itself is not listed. 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 ↗

Registered park or garden 102 m away: Chiswick 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.

Also on the record

Local nature reserve 394 m away: Leg of Mutton Reservoir; Scheduled monument 227 m away: Chiswick House; Inside the Hounslow built-up area; Public transport access: PTAL 2 (poor), TfL 2023, for the 100 m square; Designated open space 14 m away.
