Covering Hounslow
Alongside Hounslow, we also cover Isleworth, Heston (1 miles to the north-west) and Richmond.
Homes in London
Terraced houses dominate many London neighbourhoods, so most projects involve shared walls, narrow access and a party wall process. Conservation areas are widespread, and some boroughs have their own mansard and basement guidance.
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.
- Extended ridge and roof structure
- Rear dormer and roof coverings to match
- En-suite and fire-protected escape route
What is the guide price for a hip-to-gable loft conversion in Hounslow?
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 |
|---|---|
| Hip-to-gable with rear dormer | £60,000 to £80,000 |
| Double hip-to-gable (detached house) | £70,000 to £95,000 |
Planning and building rules in Hounslow
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.
- Matching old clay tiles can be difficult; reclaimed tiles are often used.
