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.

Do you need permission for a loft conversion in Portrush?

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 can change the price or programme?

The new staircase usually takes space from the landing or a bedroom below.
Fire safety rules can mean new fire doors on the floors below.

Questions about a loft conversion in Portrush

How much does a loft conversion cost?

Roughly £30,000 to £45,000 for a rooflight conversion, £50,000 to £90,000 for a dormer, £60,000 to £95,000 for a hip-to-gable and £65,000 to £110,000 for a mansard, including VAT.

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.

Can you visit a house in Portrush to quote?

Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
