Loft conversions in Cobham

Planned around your house.

Many Cobham homes have the roof height for a full loft suite with a large rear dormer and en suite. We design rear dormer, hip to gable and mansard lofts, and garage conversions, and build them with our own team.

Many dormer and hip to gable lofts fall under permitted development. Mansards, and homes in conservation areas, usually need an application to Elmbridge Borough Council. Read our planning guide.

Every loft needs building regulations approval, including a protected escape route. We design the stairs, doors and alarms to meet them.
