Double-storey extensions in Galashiels

We take on double-storey extensions in Galashiels as a complete project: survey, drawings, planning or permitted development checks, building control and the construction itself.

Covering Galashiels

Galashiels sits 13 miles north of Hawick, with Selkirk 5 miles to the south and Hawick 13 miles to the south.

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 included in a double-storey extension in Galashiels?

A double-storey extension adds new rooms on both the ground and first floor in one build, typically a larger kitchen or living space downstairs and an extra bedroom or bathroom above. Because the roof and foundations are shared, the cost per square metre is usually lower than a single-storey extension.

  • Building warrant application and completion certificate
  • Foundations, steelwork, brick and block walls, roof
  • Joining the new first floor to the existing landing

Do you need permission for a double-storey extension in Galashiels?

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 Galashiels homeowners check first?

  • Neighbours’ light is assessed using the 45-degree guide many councils use.
  • The first-floor link can mean moving a bathroom or reshaping the landing.

What are the steps?

  1. Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
  2. We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
  3. Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
  4. We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
