Hip-to-gable loft conversions in Leytonstone

Planning hip-to-gable loft conversions in Leytonstone? We design and build them for houses across London, and we fix the price for the agreed specification in writing before any building work starts.

Covering Leytonstone

Leytonstone is about 7 miles north-east of London. We also cover Walthamstow (2 miles to the north-west), Stratford and Ilford.

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 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

What approvals does a hip-to-gable loft conversion need in England?

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. 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 change the price or programme?

  • 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.

  2. Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
  3. Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
