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.
We handle a loft conversion as a managed project across Glasgow: one contract, one contact, and trades working to an agreed specification. Coverage includes Glasgow and their surroundings. In Scotland the consent rules have their own details, which we check for you. Typical prices in Scotland fall within £29,000–£62,000, VAT included, and are fixed in writing after a survey.

Homes in Glasgow
Glasgow is known for its blond and red sandstone tenements, built in large numbers in the late Victorian and Edwardian periods, alongside terraced and villa housing in the West End and Southside. Interwar cottage flats, large post-war housing schemes, high-rise blocks and newer developments make up much of the rest of the city.
Tenement flats commonly need window replacement and internal renovation, often with neighbours' agreement for shared parts. Villas and cottage flats suit kitchen and bathroom refits, loft conversions and extensions.
High rainfall and frequent wind-driven rain mean sandstone, pointing and roofs need regular care, especially on exposed elevations.
Planning and building rules in Glasgow
Which rules apply depends on where you live. For Glasgow, the answer is Scotland, and the points below reflect that; we verify them with the council before quoting.
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.
The four stages
We look at the job
Book a visit and we'll come to you. The survey covers measurements, the state of what's there now and any obvious constraints, so the price that follows is based on your actual home, not an average.
Quote in writing
We put everything into a written, fixed-price quote: the specification, what's excluded, staged payments and the expected time on site. Take whatever time you need to decide; there's no pressure to commit.
Getting ready
Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for a loft conversion are in place before the first day on site.
The work itself
The work is carried out to the agreed specification, with floors and furniture protected and the site kept tidy. At the end we clean up, walk through the finished job with you and hand over any certificates.
How we work
Frequently asked questions
Can I put a bathroom in my loft?
A bathroom or shower room can usually be added in a loft conversion if waste pipes can reach the soil stack with enough fall, or a pumped system can be used. Dormers make this easier because they give standing height for a shower. Water pressure, extraction and the position of the boiler also matter. We plan the bathroom layout at the design stage so pipes are hidden in the structure.
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.
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.
Do you cover Glasgow?
Yes. As well as Glasgow, we cover Glasgow and the rest of Glasgow. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
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.
