What is 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.

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. Building control approval is needed for every loft conversion.

What should Carrickfergus homeowners check first?

Head height under the ridge decides whether a conversion is practical.
The new staircase usually takes space from the landing or a bedroom below.

Loft conversions: common questions

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.
