What is a bungalow loft conversion?
A bungalow loft conversion uses the large roof space of a bungalow to add bedrooms and a bathroom, turning it into a chalet bungalow. Dormers at the front, rear or both create headroom; some projects raise the roof entirely.

Do you need planning permission for a bungalow loft conversion in Dumbarton?
Before anything is built in Dumbarton, we confirm which approvals apply in Scotland. In Scotland dormers on a bungalow are permitted development only on a roof slope that does not face a road and is at least 10 metres from the boundary it faces, no wider than half the roof. Front dormers and roof raises need planning permission, and a building warrant is needed before work starts.
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.
