Do I need planning permission in Dumfries?
In Scotland a building warrant from the council is needed before work starts on almost any extension, and a completion certificate is issued when the work is accepted. Building standards are set in the Scottish technical handbooks.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Building close to a public sewer needs the agreement of Scottish Water, which we check during design.
Scotland has no Party Wall Act. Where work affects a shared wall or a neighbour's land, we agree access, protection and making good with your neighbour in writing before work starts.
Applications are decided by your council as planning authority.
What is included
- Inspection bookings throughout the build
- Completion certificate on sign-off
- Building regulations drawings and written specification
- Energy and glazing checks, including whole-house calculations if needed
- Structural calculations for beams, lintels and foundations
Building regulations approval and planning permission are separate. A design can have planning consent and still need changes to meet the regulations, which is why we draw for both together.

Covering Dumfries
Site visits are available across Dumfries (DG1, DG2). The same team covers Annan (15 miles), Stranraer (57 miles), all within easy reach.
Just over the Scottish Borders border, Hawick is about 40 miles away. Scotland's housing includes sandstone villas, terraces and tenements in the cities and plenty of post-war and modern houses and bungalows elsewhere. A building warrant is needed before work starts.
How the project works
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.
Free site visit
We visit your Dumfries home, measure up, talk through what you want and check the planning position.
Design and approvals
Drawings are prepared and agreed with you, then submitted for the right planning route and building regulations approval.
Fixed written price
With the design and specification agreed, you get a fixed written price and a start date.
Build and sign-off
We build it with one project manager, book the building control inspections and hand over the completion certificate.
Questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Dumfries, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Will my neighbours in Dumfries be involved?
If a planning application is needed, the council notifies neighbours. Where work is close to a shared boundary, we agree access and protection with them in writing.
Do you cover all of Dumfries?
Yes. We cover Dumfries and the surrounding parts of Dumfries and Galloway. Site visits are free and there is no obligation.
