Velux Loft Conversion
A Velux, or rooflight, loft conversion is usually the cheapest option in Glasgow, as it works within the existing roofline and needs minimal structural alterations. It's best suited to lofts that already have good head height.
Dormer Loft Conversion
A dormer loft conversion is one of the most popular choices in Glasgow, as it adds significant headroom and floor space by extending part of the roof outwards. It suits a wide range of property types, from bungalows to semi-detached houses.
Hip-to-Gable Loft Conversion
A hip-to-gable loft conversion replaces the sloping side, or "hip", of the roof with a vertical gable wall, creating much more usable space. It's only suitable for semi-detached and detached properties with a hipped roof.
L-Shaped Dormer Loft Conversion
An L-shaped dormer combines a rear dormer with a second dormer over a rear extension, and is often used to create two bedrooms, or a bedroom with an en-suite. The extra complexity puts it towards the higher end of the price range.
Mansard Loft Conversion
A mansard loft conversion involves rebuilding the roof with steep, near-vertical walls and a flat top, creating the most additional space of any conversion type. It's a popular choice for period tenement and terraced properties, but will usually need planning permission.
For comparison, the same job typically costs around the same amount in Edinburgh, reflecting slightly lower labour rates across the north of the UK, while a loft conversion in London averages around £75,000, driven up by higher labour and material costs in the capital.
Factors That Impact Loft Conversion Costs in Glasgow
Beyond the type of conversion, several other factors affect the final price of a loft conversion in Glasgow:
- Size of the loft — larger lofts need more materials, labour and fitting out.
- Existing roof structure — a truss roof needs more time, labour and materials to convert than a traditional cut roof.
- Roof pitch and available head height — low head height often means more expensive structural work.
- Insulation and ventilation — the type and amount you choose affects the overall cost.
- Quality of fixtures and finishes — higher-spec fittings and finishes push up the final price.
- Access to the property — poor access adds to labour costs and timescales.
- Parking or access restrictions — common in Glasgow's tenement areas, and can add to costs.
- Labour rates in Glasgow and the surrounding areas — labour costs tend to be higher in the city than in more rural parts of Scotland.
As every property is different, a straightforward conversion with good head height and roof condition tends to cost less than one needing more structural work. And given Glasgow's weather, good insulation and ventilation are particularly worth prioritising.

These costs can add a substantial amount to the final price of your loft conversion, particularly a fully finished bedroom and en-suite rather than just a basic usable loft room. Adding an en-suite bathroom to any of the conversion types above typically adds a further £5,000 to £12,000 to your budget.
Do You Need Planning Permission for a Loft Conversion in Glasgow?
The majority of Glasgow properties don't require planning permission for a loft conversion. Most can be done under permitted development rights, although this depends on the specific property, scale of work and required roofline alterations.
The following require planning permission:
- Mansard conversions.
- Larger roof extensions.
- Flats or tenement properties.
- Homes in conservation areas.
- Listed buildings.
- Properties with previous extensions.
- Designs that significantly alter the roof shape or appearance.
A building warrant and building standards approval are still needed even when planning permission is not required.
Many Glasgow properties are traditional tenement flats, where the roof space is often held in common ownership under Scottish tenement law. If this applies to you, a loft conversion is likely to need planning permission (flats don't qualify for permitted development) as well as agreement from the other owners in the building, so it's worth checking your title deeds early on.
If scaffolding or a skip needs to go on a public road, you'll also need a permit from Glasgow City Council. Skip permits typically cost around £22 a week, and scaffold permits on public roads can take up to 28 working days to process, so it's worth applying well before work is due to start.

How Long Does a Loft Conversion Take?
The timeline for a loft conversion varies, depending on factors such as planning permission, building warrant approval, structural work, access, level of finish, adding an en-suite, and of course, the weather.
In general, the following are indicative timescales for various types of loft conversions:
- Velux loft conversion — around 4 to 6 weeks.
- Dormer loft conversion — around 6 to 9 weeks.
- Hip-to-gable conversion — around 7 to 9 weeks.
- L-shaped dormer conversion — around 8 to 10 weeks.
- Mansard conversion — around 8 to 12 weeks.
Adding an en-suite bathroom, or a spell of wet weather (not unusual in Glasgow), can add extra time to any of these estimates.
