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 survey and head-height check
- New floor joists, steels and staircase
- Dormer or rooflights, insulation and plasterboard

Do you need permission for a loft conversion in Magherafelt?
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.

- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
