Covering Chelsea
We work in Chelsea (SW3, SW10) and the places around it, including Battersea, Fulham and Notting Hill.
Homes in London
Much of London’s housing is Victorian and Edwardian terraces, which is why side return extensions, rear dormers and mansards are so common. Many streets are in conservation areas, and several boroughs use Article 4 directions that remove some permitted development rights.
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
- Extended ridge and roof structure
- En-suite and fire-protected escape route

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.
What should Chelsea homeowners check first?
- Matching old clay tiles can be difficult; reclaimed tiles are often used.
- The new gable is usually rendered or built in matching brick.
