What is a wraparound extension?

A wraparound extension combines a side return and a rear extension into one L-shaped addition. It gives the largest possible ground floor, often creating an open-plan kitchen, dining and living space across the whole width of the house.
How much does a wraparound extension cost in Blantyre?
In Blantyre, a wraparound extension typically costs £2,150–£3,100 per m² of floor area, including VAT at 20% (standard rate). For a typical 28 m² project that is roughly £60,000–£87,000. Prices in Scotland sit near the national average for this kind of work, and the range for Blantyre reflects that. Design, structural calculations and council fees are extra.

The biggest cost drivers are:
- Drainage changes
- Steelwork and propping of the existing house
- Total footprint and the amount of glazing
- Access for materials on terraced streets
Your exact price depends on the survey and drawings. The guide price tool gives a quick range in the meantime.
Do you need planning permission for a wraparound extension in Blantyre?
Whether you need planning permission depends on your house and its location in Scotland. In Scotland a wraparound extension normally needs planning permission and a building warrant.
Scotland has no Party Wall Act. Work on shared walls is governed by your title deeds, the Tenements (Scotland) Act 2004 for flats, and common law, so we agree arrangements with neighbours in writing before work starts.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
What we handle
From survey to sign-off, the job normally involves:
- Walls, roof and glazing
- Removal of internal and external walls
- Foundations and drainage
- Underfloor heating option, electrics and plastering
- Design and planning application
- Structural engineer’s design for steels and supports
How long does it take?
Build time is typically 12 to 18 weeks on site. Allow time beforehand for drawings and approvals, usually 3 to 4 months.
