Planning in Enfield
Straightforward permitted-development pathway for most rear extensions up to 6m. Prior approval is the common route rather than a full application.

Typical costs in Enfield
For a mid-spec 25 m² rear dormer loft conversion, all-in (structural design, building control, party wall, VAT and 12% contingency), expect roughly £90,000 to £145,000. A mansard, a hip-to-gable with high-spec en-suite joinery or a conservation-area application will push above the top of this range; a self-built rooflight conversion comes in well under the bottom.
