Homes in the South East

The South East has a lot of 1930s and post-war semi-detached housing, well suited to rear extensions and hip-to-gable loft conversions, alongside period properties in conservation areas that need a more careful design.

What does a loft conversion involve?

A loft conversion turns an unused roof space into habitable rooms, usually a bedroom with an en-suite, by strengthening the floor, adding a staircase, insulating the roof and putting in windows. The type you need depends on the roof: rooflight, dormer, hip-to-gable or mansard.

  • New floor joists, steels and staircase
  • Dormer or rooflights, insulation and plasterboard
  • En-suite, electrics, heating and fire safety upgrades

What will a loft conversion cost?

Typical ranges for loft conversions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.

Loft conversionsGuide price incl. VAT
Rooflight conversion£30,000 to £45,000
Dormer conversion£50,000 to £90,000
Hip-to-gable with dormer£60,000 to £95,000
Mansard conversion£65,000 to £110,000

What approvals does a 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.

What can change the price or programme?

  • Head height under the ridge decides whether a conversion is practical.
  • The new staircase usually takes space from the landing or a bedroom below.

How does the project run?

  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.

What people ask before starting

Is my loft suitable for conversion?

If there is about 2.2 m or more from the top of the ceiling joists to the underside of the ridge, it usually is. We check this at the free site visit.

Do I need fire doors?

Often yes. Building regulations require a protected escape route from the new floor, which usually means fire doors on to the stairs and linked smoke alarms.

Do you work in Witney?

Yes. Witney is within our coverage for loft conversions, along with nearby Oxford and Abingdon.
