Homes in the North West
Terraced housing is a defining feature of many North West towns, which brings party walls and narrow access into most projects, with more space to extend on suburban semis.
What does a wraparound extension involve?
Because it removes two external walls, a wraparound needs careful structural design and a good plan for the corner where the steels meet. We design, apply for any permissions, build and finish the shell, and can fit the kitchen as part of the same contract.
- Design, planning drawings and structural calculations
- Glazing, insulation, plastering and electrics
- Optional kitchen supply and installation
What will a wraparound extension cost?

Do you need permission for a wraparound extension in Bolton?
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.
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 should I think about before starting?
- The corner steel connection is the critical detail and is designed by a structural engineer.
- Roof water from an L-shape needs careful falls and outlets.
What are the steps?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
What people ask before starting
How much does a wraparound extension cost?
Typically £3,400 to £4,700 per square metre including VAT. Many come in between £85,000 and £120,000 before the kitchen.
Can we keep part of the kitchen working?
Often, by sequencing the work so the old back wall comes out last. We agree a plan with you before starting.
Can you visit a house in Bolton to quote?
Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
