Wraparound extension in Dumfries
We plan and build wraparound extensions for homeowners in Dumfries. An L-shaped extension that fills the side return and runs across the back. Start with a free site visit, then a written price once the design is agreed.
Dumfries and its postcode districts DG1 and DG2 are part of our Dumfries and Galloway coverage. In Dumfries we usually draw the wraparound and a simpler rear-only option side by side, so the planning risk and cost difference are clear.

How much does a wraparound extension cost in Dumfries?
For Dumfries we work from the Scotland rate: £2,090–£3,420 per square metre of new floor, including VAT, standard specification. Prices in Scotland sit a little below our West Midlands baseline; building warrant fees and drawings are budgeted separately.
| Size | Guide price inc VAT |
|---|---|
| L-shaped, about 22 m² of new floor | £46,000–£75,000 |
| L-shaped, about 30 m² of new floor | £62,500–£102,500 |
Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.
Do you need planning permission for a wraparound extension in Dumfries?
Here is how the rules in Scotland apply to a wraparound extension in Dumfries.
Scottish householder rights treat the side part of a wraparound or side infill more strictly than a plain rear extension, so most need planning permission, and all need a building warrant.
There is no Party Wall Act in Scotland; neighbour matters are handled through the title deeds, common law and written agreement before work starts.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development or a planning application, plus the building warrant.
What are homes in Dumfries like to extend?
Post-war semis and terraces are common around Dumfries, and many have room for a single-storey rear extension within Class 1A limits.

FAQ
Wraparound extension questions in Dumfries
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
How long does a rear extension take to build in Dumfries?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Does a wraparound need planning permission?
Often yes, because the side and rear parts are judged together. Some fit within permitted development; we check before drawing.
Is the site visit in Dumfries free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Do you handle building control in Dumfries?
Yes. We apply for the building warrant before work starts and submit the completion certificate at the end.
Do I need a party wall agreement?
Scotland has no Party Wall Act; we agree access and protection with your neighbour in writing instead.
