Conservation Areas

Three Rivers District has 22 conservation areas. A Conservation Area is a place of special architectural or historic interest, worthy of protection. The local authority normally makes the designation. Demolition in conservation areas normally requires Conservation Area Consent and notice of certain work to trees must be given to the Council.

No work is automatically ruled out by Conservation Area designation. However it does impose an additional requirement on residents to apply to the Council for consent and permission for certain works, and in some cases a specific Conservation Area Consent is needed.

Some permitted development rights are withdrawn, so that planning permission is needed for specific minor works which do not require planning permission elsewhere.  These include:

  • extensions over 50 cubic metres
  • outbuildings over 10 cubic metres
  • cladding
  • roof enlargement and dormer windows
  • satellite antennae in certain positions

All applications for planning permission are considered from the conservation point of view and can be refused on conservation grounds alone. This applies to planning applications not only in the conservation area itself but also in the vicinity. Permission or consent should be granted only if a proposal enhances or preserves the character or appearance of the Conservation Area. As with a planning application, an applicant has a right to appeal against a refusal, or against any conditions attached to a permission or consent.

Some Conservation Areas in the Three Rivers District are also in Article 4 areas. Specific planning regulations apply to these areas and you should speak to the Conservation Officer or a member of the Planning Department about these.
