Homes in the South East
Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.
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.
- Volume calculation and planning check
- Extended ridge and roof structure
- Rear dormer and roof coverings to match

How is a hip-to-gable loft conversion approved in Redhill?
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?
- 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 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.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
