BE4 New Development Within or on the Fringes of Conservation Areas

New development within or on the fringes of conservation areas will be expected to preserve or enhance those features which contribute to their special architectural and visual qualities; development should avoid the demolition or loss of such features. There will be a presumption in favour of retaining buildings which make a positive contribution to the character or appearance of a conservation area. Applications for planning permission should contain full details, including siting and design, or replacement buildings. Applications for consent for demolition will depend upon the submission and approval of such details.
