Homes in the East of England
Housing in the East of England ranges from post-war estates and modern developments to timber-framed and period homes in historic towns, so permitted development checks and conservation controls both feature regularly.
What does a wraparound extension involve?
A wraparound extension combines a side return and a rear extension into one L-shaped build, giving the biggest possible ground-floor space on terraced and semi-detached houses. It usually creates a large open-plan kitchen, dining and living area across the back of the house.
- Design, planning drawings and structural calculations
- Party wall process with both neighbours if needed
- Pitched, flat or glazed roof with rooflights

Do you need permission for a wraparound extension in King's Lynn?
English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.
In England a wraparound extension is treated as one extension, and because it covers both the side and the rear it does not normally fit within permitted development.
What can affect a wraparound extension?
- Roof water from an L-shape needs careful falls and outlets.
- An open-plan space this size needs a heating plan, often underfloor heating.

Wraparound extensions: common questions
Does a wraparound need planning permission?
Usually yes. In England it combines a side and rear extension, which takes it outside permitted development in most cases.
Glazed roof or solid roof?
A mix usually works best: solid roof with rooflights over the kitchen and a glazed section over the dining area.
