Is my house in a conservation area?
Type your address to check for conservation areas, listed buildings and Article 4 directions, using Historic England and government planning data. Then see what it means for your extension or loft. For permitted development limits, try our planning permission checker.
Common questions
What does a conservation area mean for my extension?
Permitted development rights are reduced. Side extensions, rear extensions of more than one storey, cladding and roof dormers need planning permission, and the council will expect a short heritage statement explaining how the design respects the area.
What is an Article 4 direction?
A council order that removes specific permitted development rights in a defined area, often inside conservation areas. Work that would normally be allowed, such as a rear extension or loft dormer, then needs a planning application.
What if my house is listed?
Most changes to a listed building, inside and out, need Listed Building Consent as well as planning permission, supported by a heritage statement.
Can I still extend in a conservation area?
Yes. Extensions and lofts are approved in conservation areas every week. Designs that are subordinate, use matching materials and keep the street view intact tend to succeed.
This checker is a guide only. Boundaries and Article 4 directions can change, so always confirm with your local council before starting work.
