Homes in the North West
Across the North West, Victorian terraces, inter-war semis and modern estates all feature, and brick or stone matching is chosen to suit each street.
What do you get with a wraparound extension?
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.
- Party wall process with both neighbours if needed
- Steel frame or goalpost for the corner opening
- Optional kitchen supply and installation

| Wraparound extensions | Guide price incl. VAT |
|---|---|
| Standard specification | £3,400 to £3,800 per m² |

| High specification | £4,250 to £4,700 per m² |
What approvals does a wraparound extension need in England?
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. Most need householder planning permission, which usually takes around eight weeks once validated.
What should I think about before starting?
- Both neighbours may need party wall notices.
- Roof water from an L-shape needs careful falls and outlets.
What are the steps?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- 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.
