Covering Chepstow
We work in Chepstow (NP16) and the places around it, including Portishead, Monmouth and Yate.
Homes in Gwent
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 goes into 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
- Extended ridge and roof structure
- Staircase, insulation, plastering and electrics
What is the guide price for a hip-to-gable loft conversion in Chepstow?
Typical ranges for hip-to-gable loft conversions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.
| Hip-to-gable loft conversions | Guide price incl. VAT |

| 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. 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 should Chepstow homeowners check first?
- The new gable is usually rendered or built in matching brick.
- Scaffolding goes up on the side of the house, which may need a neighbour’s agreement.
From first call to completion
- 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.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
