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 Newburn?
In Newburn, 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. Prices across the North East are typically 10% below the UK average for this kind of work, which is reflected in the range for Newburn. Design, structural calculations and council fees are extra.

Do you need planning permission for a wraparound extension in Newburn?
Before anything is built in Newburn, we confirm which approvals apply 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.
Where work involves a shared wall, building on the boundary, or digging foundations within 3 metres of a neighbour’s building and deeper than its foundations (or within 6 metres for deeper work), the Party Wall etc. Act 1996 applies and notices must be served 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:
- Underfloor heating option, electrics and plastering
- Party wall notices and surveyor liaison
- Design and planning application
- Structural engineer’s design for steels and supports
- Building control completion
- Removal of internal and external walls
How long does it take?
The build itself usually takes 12 to 18 weeks on site. Design and approvals come first and typically take 3 to 4 months, depending on the approval route.
