Homes in the East Midlands
Across the East Midlands you find everything from city terraces to modern estates and stone villages, so the right extension depends a lot on the street and the materials around it.
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
- Glazing, insulation, plastering and electrics
- Optional kitchen supply and installation

Do you need permission for a wraparound extension in Boston?
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 change the price or programme?
- Roof water from an L-shape needs careful falls and outlets.
- An open-plan space this size needs a heating plan, often underfloor heating.
How does the project run?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
