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 the Lothians?
Here is how the rules work for a bungalow loft conversion 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.
In Scotland a building warrant is needed before work starts on most extensions, loft conversions and conversions. It is issued by the council’s building standards service. When the work is finished, a completion certificate is submitted and accepted by the council after inspection.
We check this for your address before design work starts, so there are no surprises later.
