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 Highgate?
The approval route for Highgate is set by planning law 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.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
