What is a hip-to-gable loft conversion?
A hip-to-gable loft conversion replaces the sloping side (the hip) of a semi-detached or detached roof with a vertical gable wall. This extends the ridge and creates enough space for a staircase and a full-size room, usually combined with a rear dormer.
How much does a hip-to-gable loft conversion cost in Paisley?
In Paisley, a hip-to-gable loft conversion typically costs £53,500–£75,500 for a hip-to-gable with rear dormer, including VAT at 20% (standard rate). Prices in Scotland sit near the national average for this kind of work, and the range for Paisley reflects that. Design, structural calculations and council fees are extra.

Do you need planning permission for a hip-to-gable loft conversion in Paisley?
Approvals for a hip-to-gable loft conversion in Paisley follow the rules for Scotland. In Scotland changing a hipped roof to a gable often needs planning permission, because dormer and roof enlargement rights only apply well away from boundaries. A building warrant is needed before work starts.
Scotland has no Party Wall Act. Work on shared walls is governed by your title deeds, the Tenements (Scotland) Act 2004 for flats, and common law, so we agree arrangements with neighbours in writing before work starts.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
What we handle
From survey to sign-off, the job normally involves:
- Roof extension and rear dormer
- Survey and planning check
- Steel beams and floor joists
- Gable wall built in brick or block and finished to match
- Staircase and fire-safe escape route
- Building control sign-off
How long does it take?
Build time is typically 7 to 10 weeks on site. Before that, surveys, drawings and approvals usually take 6 to 12 weeks, longer if the council asks for changes.
