Wraparound extension in Annan
We plan and build wraparound extensions for homeowners in Annan. 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.
Annan and its postcode districts DG12 are part of our Dumfries and Galloway coverage. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in Dumfries and Galloway where a side return alone would leave the room too narrow.

Do you need planning permission for a wraparound extension in Annan?
Whether your wraparound extension in Annan needs a planning application depends on its size, your house and any local restrictions.
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 Annan like to extend?
Annan 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.

FAQ
Wraparound extension questions in Annan
Do I need planning permission for a rear extension in Annan?
Many single-storey rear extensions are permitted development under Class 1A, but not in conservation areas; you always need a building warrant before work starts.
How much does a wraparound extension cost in Annan?
As a guide, £2,090–£3,420 per square metre including VAT for a standard specification. For example, L-shaped, about 22 m² of new floor: about £46,000–£75,000 at that rate. Your written price follows the survey.
Can the corner be all glass?
Yes, with a steel or aluminium post or a structural glass corner. It needs careful thermal detailing to meet Building Regulations.
Do you handle building control in Annan?
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.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
