The Planning (Listed Building and Conservation Areas) Act 1990 creates special controls for areas designated as conservation areas. Conservation area controls apply in addition to normal planning controls.
Conservation areas can be designated by a local authority, by Historic England (only in London), or by the Secretary of State for Culture Media and Sport. There are approximately 10,000 conservation areas in England.
The National Planning Policy Framework (NPPF) states that:
'When considering the designation of conservation areas, local planning authorities should ensure that an area justifies such status because of its special architectural or historic interest, and that the concept of conservation is not devalued through the designation of areas that lack special interest.'
- Minor changes that might otherwise be considered ‘permitted development’ such as adding an extension, installing dormer windows or satellite dishes may not be permitted. Article 4 directions are used by local authorities to remove the right to permitted development. As article 4 directions are specific to particular local authorities, it is important to contact them directly to establish whether minor changes are allowed within a particular conservation area.
- Cutting down , lopping or topping trees must be notified to the local authority 6 weeks in advance so that they can consider whether the tree contributes to the character of the conservation area and whether to impose a tree preservation order.
- Proposed developments must preserve or enhance the special architectural or historic character of the conservation area. This does not specifically exclude innovative proposals but they must be sympathetic to their context.
Following the introduction of the Enterprise and Regulatory Reform Act 2013, it is no longer necessary to obtain Conservation Area Consent when demolishing unlisted buildings in conservation areas, planning permission will be required instead. Failure to obtain such permission remains a criminal offence.
Local authorities should develop policies to help preserve and enhance the character and appearance of conservation areas. Developers considering projects in conservation areas should contact the local authority conservation officer to find out what the local policies are and whether conservation area consent may be required.
When considering an application, the local authority should consider the contribution the proposals would make to preserving or enhancing the conservation area. Decisions will generally take 8 to 13 weeks, and appeals can be submitted to the Secretary of State within 6 months. Applying for conservation area consent is free.
