Hip-to-gable loft conversions in Trowbridge

Hip-to-gable loft conversions for homes in Trowbridge and the surrounding parts of Wiltshire, designed around your house and built by our teams under a single written contract.

Covering Trowbridge

Trowbridge is about 25 miles south-west of Swindon. We also cover Bath (8 miles to the north-west), Frome and Warminster.

Homes in the South West

Homes in the South West range from coastal and rural properties in stone and slate to city terraces and modern estates, so extensions are designed to match the local materials.

What does a hip-to-gable loft conversion involve?

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.

  • Gable wall build in brick, block or render
  • Staircase, insulation, plastering and electrics
  • En-suite and fire-protected escape route

Do you need permission for a hip-to-gable loft conversion in Trowbridge?

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 can affect a hip-to-gable loft conversion?

  • 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.
