Hip-to-gable loft conversions in Durham

We take on hip-to-gable loft conversions in Durham as a complete project: survey, drawings, planning or permitted development checks, building control and the construction itself.

Covering Durham

Durham is about 17 miles north of Darlington. We also cover Chester-le-Street (6 miles to the north), Houghton-le-Spring and Stanley.

Homes in the North East

The North East has terraced housing including Tyneside flats, inter-war semis and post-war estates, so loft conversions, rear extensions and layout changes are popular ways to add space.

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.

  • Extended ridge and roof structure
  • Rear dormer and roof coverings to match
  • En-suite and fire-protected escape route

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

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.

What should Durham 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.

What are the steps?

  1. Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
  2. Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
  3. Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
  4. Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
