Covering Eastbourne
We work in Eastbourne (BN21) and the places around it, including Hailsham, Seaford and Bexhill-on-Sea.
Homes in the South East
Housing across the South East mixes inter-war semis, post-war estates and older cottages in villages and market towns, so rear and side extensions, hip-to-gable lofts and garage conversions all come up regularly.
What goes into a hip-to-gable loft conversion?
Hipped roofs are common on 1930s semis and have little usable volume until the hip is squared off. We rebuild the gable in brick or block, extend the roof structure, form the rear dormer and finish the new floor, keeping the front roof slope looking as close to the original as possible.
- Volume calculation and planning check
- Gable wall build in brick, block or render
- En-suite and fire-protected escape route
What will a hip-to-gable loft conversion cost?
Guide prices for hip-to-gable loft conversions, including VAT where it applies. Your fixed price is confirmed in writing after the survey.
| 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?
Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 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.
- The new gable is usually rendered or built in matching brick.
