Development in conservation areas

To preserve the character of conservation areas there are restrictions on development, property alterations, and tree maintenance.

Conservation isn't the same as preservation. It allows some controlled changes to promote the viable use of buildings in conservation areas. If a building contributes to the character of the conservation area, we want to see it retained and maintained.

Demolition and new development

Demolition or substantial demolition of a building in a conservation area will usually need permission.

There may be cases where a building of poor quality (which contributes little to, or even detracts from, the character of the area), is proposed for demolition. Where this is agreed, and an application for a new development has been approved, the demolition and re-development applications will be processed together and their approvals linked by condition. This will only be allowed if it's considered to enhance or preserve the character and appearance of the area.

Proposals for new development should be submitted as full, not outline planning applications. They must include a design statement explaining and justifying the proposals, and drawings showing the scheme in its context - such as a street elevation.

You can use our pre-application advice service for historic buildings and places before applying for planning permission.

Property alterations

You might need planning permission to make alterations to a property if it's in a conservation area, such as:

  • adding cladding
  • inserting windows
  • installing satellite dishes and solar panels
  • adding conservatories or other extensions
  • laying paving or building walls

Find out if you need planning permission to alter your property.

Works to trees

If you want to cut down or prune a tree in a conservation area, you need to apply for permission six weeks in advance. We'll assess the contribution the tree makes to the character of the area and may decide to make a Tree Preservation Order.

You can apply for permission for works to a tree in a conservation area on the Planning Portal website.
