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 Stratford?
The approval route for Stratford 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.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
