Single-storey extensions in Galashiels

Covering Galashiels

Our coverage around Galashiels (TD1) also includes Selkirk (5 miles to the south) and Hawick.

Because the Scottish Borders 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 the Scottish Borders

Scottish homes range from city tenements and sandstone terraces to bungalows and modern estates, and the building warrant process shapes the programme for every project.

What is a single-storey extension?

We design the extension around how you use the house: where the light comes from, how the new room joins the old one, and what happens to the drains and the garden. The structure is built in brick or block to match the house, finished with a flat roof and lantern or a pitched roof, then insulated, plastered and handed back ready to decorate.

Single-storey extensions	Guide price incl. VAT

What approvals does a single-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.

Scotland has its own householder permitted development rules, and small single-storey rear extensions are often covered.

What can affect a single-storey extension?

Large glazed areas need to meet energy rules, which can shape the size of doors and rooflights.
Kitchens and doors have long lead times, so we order them early.

How does the project run?

Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.

What people ask before starting

Can we stay in the house during the build?

Usually yes. We keep the existing house closed off from the works until the knock-through near the end, and agree a temporary kitchen set-up with you if the kitchen is affected.

Do you need to dig up the drains?

Sometimes. If a public sewer runs under the extension, the water company has to agree a build-over or a diversion. We check this at survey stage.

Do you work in Galashiels?

Yes. Galashiels is within our coverage for single-storey extensions, along with nearby Selkirk and Hawick.
