A loft conversion turns unused roof space into a habitable room such as a bedroom, bathroom or office, with a proper staircase, insulation, fire protection and natural light from rooflights or a dormer.
In Galashiels, as anywhere in Scottish Borders, the price of a loft conversion is driven mainly by size, materials and access. Across Scotland our guide sits at £29,000–£62,000 with VAT, but restricted parking, a narrow side passage or extra preparation can move the figure either way. That is why every price we give follows a visit to the house.

Homes in Scottish Borders
Mill towns such as Hawick, Galashiels and Selkirk have stone terraces and tenements from the textile industry, Melrose and Kelso have older sandstone centres, and farmhouses and cottages across the Borders are built of whinstone or sandstone under slate roofs. Post-war and newer estates surround the larger towns.
Mill-town terraces and tenements often need lime repointing, re-roofing in slate and replacement windows. Newer homes commonly take extensions and garage conversions, and rural properties add fencing, porches and driveways.
None of this holds for every street in Galashiels, which is why we look at your actual house before pricing a loft conversion rather than assuming from its age alone.
Permissions for a loft conversion in Galashiels
Galashiels is in Scotland, so the planning and building rules set out below are the ones that apply. We confirm the details with the council before we quote.
In Scotland, dormers are only permitted development in limited cases (for example, at least 10 m from the boundary the dormer faces, and not in conservation areas), so many loft conversions with dormers need planning permission. Rooflight-only conversions are often simpler.
A building warrant is required for a loft conversion in Scotland, covering structure, stairs, insulation and fire safety. There is no Party Wall Act.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
From survey to handover
A visit to your home
A free survey comes first. It gives us what we need to price a loft conversion properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Written quote
After the survey we send a quote for a loft conversion that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Dates and permissions
With the quote agreed, we book the work in and handle preparation: permissions where needed, building control notifications, material orders and access arrangements for your Galashiels property.
The work itself
The job proceeds in the order set out in the programme, with dust and debris kept under control. Finally we tidy away, inspect the work together and pass the finished project over to you with its paperwork.
How we work
Common questions
Can you combine a loft conversion with other work?
Yes. Because we manage several trades under one contract, we can plan a loft conversion alongside other work on your Galashiels home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same written quote.
How much does a loft conversion cost?
A typical dormer loft conversion on a 3-bed semi costs £29,000–£62,000. A simple rooflight conversion costs less, while hip-to-gable and mansard conversions cost more because they change the roof structure. As a rough guide, allow around £800–£1,700 per square metre of new floor plus fixed costs for the staircase, steels and fees. Adding a shower room is the most common extra. We confirm a fixed price after surveying your loft.
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from a loft conversion, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
Where will the new staircase go?
The new staircase usually sits above the existing stairs, rising from the landing so it uses space that is already circulation. Sometimes it needs to come from a small bedroom or box room, which reduces that room's size. Building regulations set rules on headroom, step size and handrails, with some flexibility for lofts. We look at options at the survey and show you how each affects the floor below.
Do I need planning permission for a loft conversion?
Whether a loft conversion needs planning permission depends on its size and design, your home's location, whether it is listed or in a conservation area, and which UK nation you live in. In England, many conversions fall under permitted development if the added volume is within 40m³ for terraced houses or 50m³ for other houses and nothing extends beyond the front roof slope. We check what applies before quoting.
