Conservation areas are defined in the Town and Country Planning Acts as "areas of special architectural or historic interest, the character or appearance of which it is desirable to preserve or enhance". They are a unique form of conservation because they not only protect listed buildings. They include unlisted buildings, open spaces, trees and special features that make an area locally distinctive.
Local planning authorities are required to designate conservation areas where it is considered appropriate within the areas that they cover. They all have their own individual Conservation Area Appraisals, which define their special architectural and historic character. Each appraisal has been adopted by the council as a supplementary planning document and is intended to be used a guide for residents and those wanting to make a planning application for a site within a conservation area. The appraisals have a useful summary map at the back which is worth referring to for a quick guide.
Our conservation areas are reviewed from time to time to look at their boundaries and to update and improve their appraisals. We also consider the designation of new conservation areas following requests to do so by parish councils or through neighbourhood plans.
You can use our Geographic Information System to view online maps of conservation areas.
