Most homeowners are surprised to learn that knocking a building down is often simpler on paper than putting one up, but it is rarely paperwork free. Whether you need planning permission depends on what the building is, where it sits in the Ribble Valley, and what you plan to do afterwards. This guide sets out the rules as they apply in England and what actually happens on the ground.
Demolition counts as development in law, but for most houses and outbuildings it falls under permitted development, so a full planning application is not needed. The main exception is that demolishing a whole house or a building over 50 cubic metres triggers a separate process called prior notification, which we cover below.
Small structures are the easiest case. A detached garage, shed, greenhouse or lean-to under 50 cubic metres can normally be taken down without telling the council at all, provided it is not listed and you are not in a conservation area. Around Clitheroe that covers a large share of the jobs we quote, from tired concrete sectional garages to collapsing stone outbuildings on farm plots.
For a dwelling, or any building larger than 50 cubic metres, you have to apply to Ribble Valley Borough Council for a prior approval determination before work starts. This is not a full planning application. You submit a written description of the proposed demolition, a site plan, a statement of how you intend to carry it out and how the site will be restored afterwards. The council has 28 days to decide whether it wants to approve your method of demolition and site restoration.
You also need to display a site notice on or near the building for at least 21 days during that window, and the application itself carries a modest fee, currently around 120 pounds. If the council does not respond within 28 days you can proceed. In practice we prepare the method statement for clients because the council will expect to see how you deal with dust, noise, neighbouring walls and traffic on narrow lanes like those off Whalley Road or Waddington Road.
The Ribble Valley has one of the highest concentrations of listed buildings in Lancashire, and Clitheroe town centre, Waddington, Downham, Whalley and Slaidburn all have conservation areas. If your building is listed, demolishing all or part of it without listed building consent is a criminal offence, and that applies to a stone barn attached to a listed farmhouse just as much as to the farmhouse itself.
In a conservation area, demolishing an unlisted building larger than 115 cubic metres, or any wall or fence over one metre next to a highway or two metres elsewhere, needs planning permission specifically for the demolition. Many of the old boundary walls in Downham and Waddington fall into this category. Check the Ribble Valley planning map before you assume a boundary wall or outbuilding is fair game.
Separate from planning, the Building Act 1984 requires you to give building control at the council at least six weeks notice before demolishing any building larger than 50 cubic metres. This is a legal requirement, and the council can issue a counter notice with conditions about shoring adjoining structures, weatherproofing exposed walls and disconnecting services safely. You will also need to arrange disconnection of gas, electricity and water with the utility companies, which can take two to four weeks on its own.
Any building built or refurbished before 2000 must have an asbestos refurbishment and demolition survey before work starts. Older stone properties and 1960s garages around Clitheroe often contain asbestos cement roofing or insulating board, and a survey typically costs between 200 and 600 pounds depending on the size of the building. If bats or nesting birds are present, which is common in barns and older roofs across the Forest of Bowland fringe, an ecological survey may be needed and timing may be restricted to outside the breeding season.
Because the prior notification, building control notice and utility disconnections can run in parallel, a straightforward house demolition can usually go from first enquiry to machines on site in six to ten weeks. Listed building consent or a conservation area application adds eight weeks at minimum and often considerably more. Small outbuildings can often be dealt with in a fortnight once the asbestos position is known.
On cost, a detached garage in the Clitheroe area typically comes in somewhere between 1,500 and 4,000 pounds depending on access and any asbestos, while a full house demolition with slab removal and site clearance is more often in the 12,000 to 30,000 pound range. The biggest variables are asbestos removal, how close neighbouring buildings are, and how much muck has to be carted away over rural roads. A reputable contractor will walk you through which approvals apply before quoting rather than leaving you to find out from an enforcement letter.
No. Even where planning permission is not required, you must submit a prior notification to Ribble Valley Borough Council and a demolition notice to building control, and arrange utility disconnections before work starts.
Outside a conservation area, generally not. Inside one, walls over one metre high next to a road or two metres elsewhere need planning permission, so check the conservation area map for your village first.
The council can serve an enforcement notice, and for listed buildings or conservation area breaches you can face prosecution with unlimited fines. It can also complicate any later application to rebuild on the site.
