Double-storey extensions in Dalbeattie

Covering Dalbeattie

We work in Dalbeattie (DG5) and the places around it, including Dumfries, Annan and Workington.

Because Dumfries and Galloway covers a wide area, we confirm availability after the first call and include any travel costs in the written quote rather than adding them later.

Homes in Dumfries and Galloway

In Scotland many families extend bungalows and semis, while tenement flats bring shared ownership of roofs and walls that needs agreeing early.

What goes into a double-storey extension?

Two-storey work has to sit comfortably with the house and the neighbours, so most of the design effort goes into the roofline, window positions and how the new first floor connects to the landing. We handle the planning application, the structural design and the building control process, then build, roof and finish both floors.

What will a double-storey extension cost?

Use these ranges to budget for double-storey extensions; the survey turns them into a fixed price for the agreed specification.

Double-storey extensions	Guide price incl. VAT
Standard specification	£2,400 to £2,900 per m²
Good specification	£2,900 to £3,400 per m²
High specification	£3,400 to £3,850 per m²

What approvals does a double-storey extension need in Scotland?

Scottish projects follow a different process from England: the council issues a building warrant before work starts and accepts a completion certificate at the end, alongside any planning permission needed. We prepare both applications.

Two-storey extensions in Scotland almost always need planning permission, and a building warrant must be granted before work starts.

What should I think about before starting?

Side extensions close to a boundary are often set back or stepped down so they do not create a terraced effect.
The first-floor link can mean moving a bathroom or reshaping the landing.
