Historic England ↗

Mayfair conservation area

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.

Council document ↗

2 Article 4 directions

Article 4 Basement Development Permitted Rights Removed · Article 4 Direction Class E To C3 In Central Activities Zone. Named permitted development rights are withdrawn here.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: City of Westminster APA 2.5

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: Westminster 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.
