Homes in Dunbartonshire
In Scotland many families extend bungalows and semis, while tenement flats bring shared ownership of roofs and walls that needs agreeing early.
What do you get with a loft conversion?
We start with the head height. You need roughly 2.2 m or more from the top of the ceiling joists to the underside of the ridge for a conversion to work without raising the roof. From there we design the staircase position, the type of conversion and the en-suite, and manage the whole build including fire safety and building control.
- Design drawings and structural calculations
- Dormer or rooflights, insulation and plasterboard
- En-suite, electrics, heating and fire safety upgrades
How much should I budget for a loft conversion?
What loft conversions typically cost. These are guide ranges; the written quote for your house replaces them.
| Loft conversions | Guide price incl. VAT |
|---|---|
| Rooflight conversion | £30,000 to £45,000 |
| Dormer conversion | £50,000 to £90,000 |
| Hip-to-gable with dormer | £60,000 to £95,000 |
| Mansard conversion | £65,000 to £110,000 |
What approvals does a loft conversion 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.
In Scotland, dormers and other roof enlargements usually need planning permission, especially on the front of the house. A building warrant is needed before work starts in every case.
What can affect a loft conversion?
- Head height under the ridge decides whether a conversion is practical.
- The new staircase usually takes space from the landing or a bedroom below.
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.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
