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 conversions: common questions

Can we live at home during a loft conversion?

Yes. Most of the work is done from scaffolding until the staircase goes in near the end.

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 Coleraine?

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