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.
- Loft survey and head-height check
- Dormer or rooflights, insulation and plasterboard
- En-suite, electrics, heating and fire safety upgrades

Do you need permission for a loft conversion in Bonnyrigg?
Projects in Scotland need a building warrant from the council before any building work starts, and a completion certificate once it is finished. Planning permission is a separate decision. The Party Wall etc. Act does not apply in Scotland; shared walls are governed by title deeds and the law of the tenement where relevant.
In Scotland, dormers and other roof enlargements usually need planning permission, especially on the front of the house.
What should Bonnyrigg homeowners check first?
