Loft conversions in Bournemouth

Covering Bournemouth

We work in Bournemouth (BH1, BH2, BH7) and the places around it, including Christchurch, Poole and Wimborne Minster.

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 loft conversion involve?

We start with the head height. You need roughly 2.2 m or more from the top of the ceiling joists to the underside of the ridge for a conversion to work without raising the roof. From there we design the staircase position, the type of conversion and the en-suite, and manage the whole build including fire safety and building control.

How is a loft conversion approved in Bournemouth?

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.
Party wall notices are often needed for steels bearing on a shared wall.

Questions about a loft conversion in Bournemouth

Does a loft conversion need planning permission?

In England many are permitted development, within 40 m³ of extra volume on a terrace or 50 m³ on a semi or detached house. Conservation areas and flats need permission.

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.

Use the guide price tool for a ballpark figure, then book a visit for a fixed written price for the agreed specification.
