Homes in South Glamorgan
Welsh homes include long terraces built into hillsides, stone cottages and modern estates, and sloping sites often shape how and where an extension can go.
What does a hip-to-gable loft conversion involve?
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.
- Gable wall build in brick, block or render
- Staircase, insulation, plastering and electrics
- En-suite and fire-protected escape route
What will a hip-to-gable loft conversion cost?
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?
In Wales the planning rules, including what counts as permitted development, are set by the Welsh Government, and Welsh building regulations differ in places from England’s. We check both against your house before drawings are finalised, and handle party wall notices where needed.
Wales has its own loft and roof permitted development rules.
What can change the price or programme?
- Matching old clay tiles can be difficult; reclaimed tiles are often used.
- The new gable is usually rendered or built in matching brick.
