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 Gateshead?
In Gateshead, 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. Building costs in the North East run about 10% below the UK average, and the figures for Gateshead are adjusted to reflect that. Design, structural calculations and council fees are extra.

- Steelwork and propping of the existing house
- Drainage changes
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 Gateshead?
The approval route for Gateshead is set by planning law 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.

Almost always. Combining side and rear elements usually goes beyond permitted development limits, so a householder planning application is normally made.

The side wall of the back addition is usually removed and replaced with a steel beam, so the old kitchen joins the new space.
