Can I extend a house in South Brent?

For anyone buying or renting in South Brent.

Yes, though the paperwork gets a vote. The area holds more than 150 listed buildings, with a conservation area sitting over the middle of the village and scheduled monuments scattered across the moor above it. People here alter their homes regularly, and they do it through the planning system rather than around it. Which of those categories your house sits in decides everything about how hard it will be. All of it is knowable before you offer.

There are 160 listed buildings across the area. Five carry Grade I, three are Grade II star, and 152 are Grade II. Listing covers the whole building, inside as well as out, and generally what is attached to it, so consent is needed for work that would be nobody's business a mile up the road. Windows, internal walls, roof coverings. The grade affects how much scrutiny turns up, not whether you need permission in the first place.

One conservation area covers South Brent itself. Inside it, some of the permitted development rights that apply everywhere else are trimmed back, and things like demolishing a wall or outbuilding, or working on trees, need consent that the identical job would not need outside the boundary. Materials and detailing stop being a choice and become a conversation.

Eight scheduled monuments sit within the area, most of them prehistoric cairns and hut circles on the moor, including the cluster around Corringdon Ball. Scheduled monument consent is the strictest protection in the system, and it matters mainly if your land runs up against one rather than if you live in the village.

The planning system here is used rather than avoided. The record shows 135 applications across the area between April 2024 and June 2026, with 61 of them falling in the most recent twelve months. Altering a house here is ordinary business, not an act of local rebellion.

Mining legacy is a footnote rather than a chapter. Under 1% of postcodes have a recorded mine entry within 500 metres, the nearest recorded working sits about 190 metres from a postcode, and none of them sit directly over one. This is not a coalfield. What it means in practice is that a mining search may return something worth reading, occasionally a specialist report, and that this tends to concern a lender or an insurer well before it concerns a builder.

Three listed buildings in the area appear on Historic England's Heritage at Risk register. That is a judgement about the condition of those particular buildings, and it can open the door to grant support for repairs along with a good deal of attention. It says nothing about an ordinary house on the same lane, whatever the layout of a search report might imply.

For most houses here the standard permitted development rules apply and a modest extension runs through the usual process. For a listed house, permitted development is largely beside the point and consent comes before drawings. Inside the conservation area you are in the middle case, where some of what you could do freely elsewhere needs asking about first. The order of operations does not change: find out exactly what the address is designated as before you pay an architect, not after the plans come back.

Freedom to alter a house in South Brent is on the tight side, and the constraint is designation rather than anyone's mood at the council. Buy the house you want to live in rather than the one you intend to rearrange, unless you have already read what it is listed as.
