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 Newcastle upon Tyne?
In Newcastle upon Tyne, 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. That range is adjusted for the North East, where domestic building work typically costs around 10% below the national average. Design, structural calculations and council fees are extra.

Do you need planning permission for a wraparound extension in Newcastle upon Tyne?
Before anything is built in Newcastle upon Tyne, 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.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
