Living in a conservation area doesn't stop you improving your home. But it changes almost everything about how you do it. Works that would be permitted development anywhere else — replacing windows, adding cladding, building a side extension — require planning permission in a conservation area. And enforcement for unapproved works in conservation areas is more actively pursued than almost anywhere else.
A conservation area is an area of special architectural or historic interest designated by the local planning authority under Section 69 of the Planning (Listed Buildings and Conservation Areas) Act 1990. There are over 10,000 conservation areas in England. Being in a conservation area does not mean your house is listed — most houses in conservation areas are not listed — but it does significantly affect your permitted development rights.
Most internal works remain unrestricted. Permitted development rights retained in a conservation area include rear extensions on rear elevations not visible from a highway, loft conversions on rear and side slopes not visible from a highway, outbuildings and garden rooms in the rear garden not visible from a highway, solar panels on rear roof slopes not visible from a highway, and fences and walls up to standard height limits.
Any extension on a side elevation visible from a highway. Cladding the exterior with any material. Demolishing any building or wall over a certain size. Adding a satellite dish visible from a highway. Adding a rooflight on a front-facing slope visible from a highway. Replacing windows or doors where visible from a highway. Any works that materially alter the external appearance as seen from a highway.
The key restriction in conservation areas is visibility from a highway — including footpaths, bridleways, and side streets, not just main roads. Enforcement in conservation areas is active. Window replacements, cladding, and satellite dishes are the most common subjects of conservation area enforcement notices. The requirement to reinstate original features at the current owner\'s cost is frequently imposed.
Many conservation areas have Article 4 Directions that remove even the remaining permitted development rights. In a conservation area with an Article 4 Direction, almost any external alteration to the house requires planning permission. Conservation area status and Article 4 Directions both appear in the planning history.
