Across Wales you find valley terraces, coastal towns, rural stone houses and newer estates, so access, slopes and local materials all feature in the design.
What do you get with a hip-to-gable loft conversion?
A hip-to-gable loft conversion rebuilds the sloping side (the hip) of a semi-detached or detached house roof as a vertical gable wall, extending the ridge and creating enough space for a staircase and rooms. It is usually combined with a rear dormer.
- Planning and building regulations checks under Welsh rules
- Gable wall build in brick, block or render
- Extended ridge and roof structure
How much should I budget for a hip-to-gable loft conversion?
Use these ranges to budget for hip-to-gable loft conversions; the survey turns them into a fixed price for the agreed specification.
| Hip-to-gable loft conversions | Guide price incl. VAT |
|---|---|
| Hip-to-gable with rear dormer | £60,000 to £80,000 |
| Double hip-to-gable (detached house) | £70,000 to £95,000 |
What approvals does a hip-to-gable loft conversion need in Wales?
Planning decisions in Wales are made by the local council, using permitted development rules set by the Welsh Government rather than England’s. Building regulations in Wales have their own approved documents, and the Party Wall etc. Act 1996 applies to work on shared walls and boundaries.
Wales has its own loft and roof permitted development rules. Rear dormers within set volume limits are often allowed, but the detail differs from England's, so we confirm the current Welsh limits against your roof before the design is fixed.
What can affect a hip-to-gable loft conversion?
- Matching old clay tiles can be difficult; reclaimed tiles are often used.
- The new gable is usually rendered or built in matching brick.
What are the steps?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
