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 Limavady?
In Limavady, a wraparound extension typically costs £1,900–£2,750 per m² of floor area, including VAT at 20% (standard rate). For a typical 28 m² project that is roughly £53,000–£77,000. Building costs in Northern Ireland run about 14% below the UK average, and the figures for Limavady are adjusted to reflect that. Design, structural calculations and council fees are extra.
