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 Scunthorpe?
In Scunthorpe, a wraparound extension typically costs £2,100–£3,050 per m² of floor area, including VAT at 20% (standard rate). For a typical 28 m² project that is roughly £59,000–£85,500. The guide for Scunthorpe reflects typical costs in the East Midlands, roughly 5% below the UK-wide figure. Design, structural calculations and council fees are extra.

|---|---|
| Smaller project (20 m²) | £42,000–£61,000 |

| Larger project (39 m²) | £82,000–£119,000 |

The biggest cost drivers are:
- Kitchen and flooring specification
- Access for materials on terraced streets
- Steelwork and propping of the existing house
- Total footprint and the amount of glazing
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 Scunthorpe?
Here is how the rules work for a wraparound extension in England. In England a wraparound extension combines side and rear elements, which normally takes it outside permitted development, so a householder planning application is made.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
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:
- Underfloor heating option, electrics and plastering
- Foundations and drainage
- Walls, roof and glazing
- Design and planning application
- Removal of internal and external walls
- Building control completion
How long does it take?
Build time is typically 12 to 18 weeks on site. Before that, surveys, drawings and approvals usually take 3 to 4 months, longer if the council asks for changes.

Questions about wraparound extensions in Scunthorpe
Is a wraparound worth it?
It gives the biggest ground-floor space without going upwards. Whether it adds value depends on your street and house, so we suggest checking local sale prices before committing.
What about the old back addition?
The side wall of the back addition is usually removed and replaced with a steel beam, so the old kitchen joins the new space.
