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 Potters Bar?
Whether you need planning permission depends on your house and its location in England. In England rear dormers on a bungalow are often permitted development within the 50 cubic metre volume limit. Front dormers, roof raises and conservation-area work need planning permission.
Where work involves a shared wall, building on the boundary, or digging foundations within 3 metres of a neighbour’s building and deeper than its foundations (or within 6 metres for deeper work), the Party Wall etc. Act 1996 applies and notices must be served before work starts.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
