Covering Devon
Our coverage across Devon includes Plymouth, Exeter, Paignton and Torquay.
Homes in the South West
In the South West, matching local stone, render or slate is often the main design question, and conservation areas and listed buildings are common in historic towns.
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.
- Rear dormer and roof coverings to match
- Staircase, insulation, plastering and electrics
- En-suite and fire-protected escape route
How much does a hip-to-gable loft conversion cost in Devon?
Indicative costs for hip-to-gable loft conversions. London and the South East usually sit towards the top of each range.
| 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 England?
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 can affect a hip-to-gable loft conversion?
- Hip-to-gable volume counts towards the permitted development allowance.
- Scaffolding goes up on the side of the house, which may need a neighbour’s agreement.
What happens after I enquire?
- 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.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
Questions about a hip-to-gable loft conversion in Devon
Does a hip-to-gable need planning permission?
In England it is often permitted development if the total extra volume stays within 50 m³ for a semi or detached house.
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 Devon 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.
