Homes in the East Midlands

Across the East Midlands you find everything from city terraces to modern estates and stone villages, so the right extension depends a lot on the street and the materials around it.

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.

  • Loft survey and head-height check
  • Dormer or rooflights, insulation and plasterboard
  • En-suite, electrics, heating and fire safety upgrades

How much should I budget for a loft conversion?

Do you need permission for a loft conversion in Alfreton?

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 should I think about before starting?

  • Head height under the ridge decides whether a conversion is practical.
  • Fire safety rules can mean new fire doors on the floors below.

What happens after I enquire?

  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. We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.

Loft conversions: common questions

How long does a loft conversion take?

Usually 6 to 14 weeks on site depending on the type.

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.

Who deals with the council for a project in Alfreton?

We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
