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 Newtownards?
In Newtownards, 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. Prices across Northern Ireland are typically 14% below the UK average for this kind of work, which is reflected in the range for Newtownards. Design, structural calculations and council fees are extra.

Do you need planning permission for a wraparound extension in Newtownards?
Before anything is built in Newtownards, we confirm which approvals apply in Northern Ireland. In Northern Ireland a wraparound extension normally needs planning permission and building control approval.
Northern Ireland has no Party Wall Act. Work on shared walls relies on agreement with the neighbour and common law, so we agree the arrangements in writing before work starts.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.

Questions about wraparound extensions in Newtownards
Can we keep a separate living room?
Yes. Many clients keep the front room separate and open up only the back of the house.
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.
