Dumfries and Galloway has sandstone villas and terraces, post-war semis and four-in-a-block flats. Flats need planning permission for an extension, and every project needs a building warrant before work starts.
What does it cost in Dumfries and Galloway?
As a guide, £1,000–£2,500 including VAT. We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
Do you need planning permission in Dumfries and Galloway?
Scottish Class 1B rights for extensions of more than one storey need a 10 metre gap to every boundary, which few gardens have. Expect a planning application as well as a building warrant for a double-storey rear extension.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent.
Planning and building warrant fees in Scotland are set nationally and by value of work; we confirm both before submitting.
Scottish councils aim to decide householder applications within two months; the building warrant runs alongside.
