What is a rooflight loft conversion?
A rooflight loft conversion (sometimes called a roof window conversion) keeps the existing roof shape and adds roof windows that sit flush with the slope. The floor is strengthened, a staircase is added and the space is insulated and finished.

Do you need planning permission for a rooflight loft conversion in Arbroath?
Approvals for a rooflight loft conversion in Arbroath follow the rules for Scotland. In Scotland rooflights that project no more than 1 metre from the roof are often permitted development, though conservation areas and listed buildings need consent. A building warrant is needed for the conversion itself.
Scotland has no Party Wall Act. Work on shared walls is governed by your title deeds, the Tenements (Scotland) Act 2004 for flats, and common law, so we agree arrangements with neighbours in writing before work starts.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
