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.

  • Design drawings and structural calculations
  • Planning or lawful development certificate
  • New floor joists, steels and staircase

Planning and building rules in Thatcham

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 loft conversion?

  • The new staircase usually takes space from the landing or a bedroom below.
  • Fire safety rules can mean new fire doors on the floors below.

What people ask before starting

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.
