What goes into a loft conversion?
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.
- Planning and building control applications to the council
- Design drawings and structural calculations
- En-suite, electrics, heating and fire safety upgrades

What approvals does a loft conversion need in Northern Ireland?
Northern Ireland projects need planning clearance and building control approval from the local council. We prepare the applications and agree any work near neighbouring property directly with the neighbours.
In Northern Ireland, roof enlargements such as dormers often need planning permission depending on size and position.

- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
What people ask before starting
Is my loft suitable for conversion?
If there is about 2.2 m or more from the top of the ceiling joists to the underside of the ridge, it usually is. We check this at the free site visit.
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.
Who deals with the council for a project in Limavady?
We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
