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 Jarrow?
In Jarrow, a wraparound extension typically costs £2,000–£2,900 per m² of floor area, including VAT at 20% (standard rate). For a typical 28 m² project that is roughly £56,000–£81,000. We start from a UK-wide guide and adjust it for the North East, where labour and materials are typically about 10% below average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| Smaller project (20 m²) | £40,000–£58,000 |

| Larger project (39 m²) | £78,000–£113,000 |
| Rate per m² | £2,000–£2,900 |
What moves the price most:
- Drainage changes
- Steelwork and propping of the existing house
- Total footprint and the amount of glazing
- Kitchen and flooring specification
A guide range is only a starting point: the guide price tool gives an instant figure for your size, and a free survey turns it into a fixed quote.
Do you need planning permission for a wraparound extension in Jarrow?
Whether you need planning permission depends on your house and its location 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:
- Walls, roof and glazing
- Building control completion
- Underfloor heating option, electrics and plastering
- Party wall notices and surveyor liaison
- Removal of internal and external walls
- Foundations and drainage
How long does it take?
The build itself usually takes 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.

What about the old back addition?
