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 Craigavon?
In Craigavon, 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. That range is adjusted for Northern Ireland, where domestic building work typically costs around 14% below the national average. Design, structural calculations and council fees are extra.

Do you need planning permission for a wraparound extension in Craigavon?
Here is how the rules work for a wraparound extension 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.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
What we handle
On a typical wraparound extension we handle:
- Removal of internal and external walls
- Written agreement with neighbours on shared walls
- Walls, roof and glazing
- Structural engineer’s design for steels and supports
- Underfloor heating option, electrics and plastering

How long does it take?
Allow 12 to 18 weeks on site. Before that, surveys, drawings and approvals usually take 3 to 4 months, longer if the council asks for changes.

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