Extending a house in a Bristol conservation area

How do I know if I'm in a conservation area?

Bristol City Council publishes maps of its conservation areas on its website. Large parts of Clifton, Hotwells, Cotham, Redland, Kingsdown and Montpelier are covered, along with smaller areas across the city. If you are not sure, we can check for you.

What changes compared with an ordinary street?

Some work that would normally be permitted development needs a planning application in a conservation area. This includes side extensions, extensions of more than one storey at the rear, cladding the outside of the house, and dormer windows on the roof. Single-storey rear extensions can still be permitted development within the usual limits.

Demolishing all or most of a building in a conservation area also needs planning permission, and you must give the council six weeks' notice before cutting down or pruning most trees.

Article 4 directions

Some Bristol streets also have Article 4 directions. These remove specific permitted development rights, often for front windows and doors, front boundary walls and roof alterations, so that the character of the street is protected. If your house is covered, even like-for-like looking changes may need permission.

What the council looks for

The test is whether the proposal preserves or enhances the character and appearance of the area. In practice that means an extension that is subordinate to the house, uses suitable materials, and is not prominent from the street. Rear extensions are usually easier than side or front additions.

How to give your application the best chance

Start with an accurate measured survey, look at what neighbours have been allowed to build, and keep the design in proportion with the house. Include a short heritage statement explaining why the proposal suits the area. For anything unusual, the council's pre-application advice service can save time later.
