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.

In Dunbartonshire, a bungalow loft conversion typically costs £43,500–£77,500 for a typical bungalow conversion with dormers, including VAT at 20% (standard rate).

Do you need planning permission for a bungalow loft conversion in Dunbartonshire?
The approval route for Dunbartonshire is set by planning law 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.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
