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 Scarborough?
In Scarborough, a wraparound extension typically costs £2,050–£3,000 per m² of floor area, including VAT at 20% (standard rate). For a typical 28 m² project that is roughly £57,500–£84,000. Prices across Yorkshire and the Humber are typically 7% below the UK average for this kind of work, which is reflected in the range for Scarborough. Design, structural calculations and council fees are extra.

Do you need planning permission for a wraparound extension in Scarborough?
Before anything is built in Scarborough, 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.
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.

Questions about wraparound extensions in Scarborough
How much does a wraparound extension cost in Scarborough?
In Scarborough, a wraparound extension typically costs £2,050–£3,000 per m² of floor area, including VAT at 20% (standard rate). A typical 28 m² project comes to roughly £57,500–£84,000. 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.
Who approves a wraparound extension in Scarborough?
Planning matters in Scarborough go to the council covering your address, and the work needs building control approval. We prepare and submit the applications for you.
Can we keep a separate living room?
Yes. Many clients keep the front room separate and open up only the back of the house.
Will both neighbours be affected?
Usually only the neighbour on the side return side, but rear foundations near either boundary can trigger party wall notices.
