Site constraints 10

Green belt: London

Inappropriate development needs very special circumstances.

Green belt policy allows a short list of exceptions, such as limited extensions and replacement buildings. Anything else needs very special circumstances that clearly outweigh the harm. Some green belt land can count as grey belt, where it does not strongly serve the green belt's purposes. The council decides this in its green belt assessment or on each application, so we do not mark it here.

Read the government guidance ↗

Cowley Lock conservation area

Also Cowley Lock. 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

Residential extensions · Houses of Multiple Occupation (HMOs). Named permitted development rights are withdrawn here.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.

Priority habitat: Deciduous woodland

A habitat of principal importance. It shapes the ecology work and the biodiversity net gain a scheme has to show.

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: Hillingdon 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.

Habitat network: Other Priority Habitats -NEX

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

Also on the record

A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
