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 Whitley Bay?
In Whitley Bay, 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 Whitley Bay are adjusted to reflect that. Design, structural calculations and council fees are extra.

Questions about wraparound extensions in Whitley Bay
How much does a wraparound extension cost in Whitley Bay?
In Whitley Bay, a wraparound extension typically costs £2,000–£2,900 per m² of floor area, including VAT at 20% (standard rate). A typical 28 m² project comes to roughly £56,000–£81,000. Your fixed price depends on the survey and drawings.
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.
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.
Can we keep a separate living room?
Yes. Many clients keep the front room separate and open up only the back of the house.
Who approves a wraparound extension in Whitley Bay?
Planning matters in Whitley Bay go to the council covering your address, and the work needs building control approval. We prepare and submit the applications for you.
