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 Lincoln?
In Lincoln, a wraparound extension typically costs £2,100–£3,050 per m² of floor area, including VAT at 20% (standard rate). For a typical 28 m² project that is roughly £59,000–£85,500. That range is adjusted for the East Midlands, where domestic building work typically costs around 5% below the national average. Design, structural calculations and council fees are extra.

Questions about wraparound extensions in Lincoln
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.
How long does a wraparound extension take in Lincoln?
Typically 12 to 18 weeks on site. Design and approvals beforehand usually take 3 to 4 months.
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.
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.
