What is a loft conversion?

We start with the head height. You need roughly 2.2 m or more from the top of the ceiling joists to the underside of the ridge for a conversion to work without raising the roof. From there we design the staircase position, the type of conversion and the en-suite, and manage the whole build including fire safety and building control.

What approvals does a loft conversion need in Scotland?

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. A building warrant is needed before work starts in every case.
