Covering Chiswick
We work in Chiswick (W4) and the places around it, including Acton, Barnes and Shepherd's Bush.
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.
- Volume calculation and planning check
- Gable wall build in brick, block or render
- Extended ridge and roof structure
What is the guide price for a hip-to-gable loft conversion in Chiswick?

How is a hip-to-gable loft conversion approved in Chiswick?
English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.
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 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.
What are the steps?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- 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.
