What does a dormer loft conversion involve?
A dormer loft conversion builds a box-shaped extension out from the rear slope of the roof, creating vertical walls and full head height across most of the new floor. It is the most popular type of loft conversion because it gives the most usable space for the cost.
- Steelwork and new floor structure
- Dormer frame, roof covering and cladding
- Staircase, insulation and plasterboard

Do you need permission for a dormer loft conversion in Motherwell?
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.
