Covering Wiltshire
Our coverage across Wiltshire includes Swindon, Salisbury, Trowbridge and Chippenham.
Homes in the South West
Homes in the South West range from coastal and rural properties in stone and slate to city terraces and modern estates, so extensions are designed to match the local materials.
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.
- Gable wall build in brick, block or render
- Rear dormer and roof coverings to match
- Staircase, insulation, plastering and electrics
What is the guide price for a hip-to-gable loft conversion in Wiltshire?
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 |
Do you need permission for a hip-to-gable loft conversion in Wiltshire?
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.
In England many loft conversions are permitted development: the extra roof volume must stay within 40 m³ on a terraced house or 50 m³ on a semi or detached house, nothing can sit higher than the existing ridge, no dormer can face a road on the main elevation, and side windows must be obscure-glazed and non-opening below 1.7 m. Houses in conservation areas, National Parks and National Landscapes cannot use these roof-extension rights, so dormers there need planning permission (a rooflight-only conversion can still be permitted development), and flats always need permission.
What should I think about before starting?
- Matching old clay tiles can be difficult; reclaimed tiles are often used.
- Scaffolding goes up on the side of the house, which may need a neighbour’s agreement.

Hip-to-gable loft conversions: common questions
How long does it take?
About 9 to 13 weeks on site.
Will the roof tiles match?
We match the tiles as closely as possible, using reclaimed tiles where the originals are no longer made.
Can you visit a house in Wiltshire to quote?
Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
