The sloping side roof is built up into a straight gable wall, then a rear dormer goes on the back.

Three-bed semis and terraces
A box built out from the back roof slope, giving full standing height and the most floor space.

A dormer that wraps the main roof and the back addition, so the new room runs in an L.

Planning in Carshalton
Carshalton is in the area of the London Borough of Sutton. Most loft conversions don't need planning permission: they count as permitted development if they stay within the size and design rules. That changes if your house is in a conservation area (London Borough of Sutton has several, including Carshalton Village), or if the council has removed permitted development rights with an Article 4 direction.
Sutton also has Areas of Special Local Character as well as conservation areas, so it's worth checking your road before you plan a dormer that faces the street.
- We check your road at the free feasibility visit and tell you straight away if you need a planning application.
- Our in-house architect, Simon Burrows, draws up your loft, and Mark goes through the drawings with you, including whether permitted development applies.
- Every loft needs building regulations approval. We handle it through independent building control, start to finish.
