Wraparound extension in Antrim
An L-shaped extension that fills the side return and runs across the back. We design, get the approvals for and build wraparound extensions in Antrim and the surrounding area, with one contract from the first survey to building control sign-off.
Antrim is covered from our County Antrim round, including BT41. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in County Antrim where a side return alone would leave the room too narrow.

Do you need planning permission for a wraparound extension in Antrim?
Whether your wraparound extension in Antrim needs a planning application depends on its size, your house and any local restrictions.
In Northern Ireland side extensions that face a road, or go beyond permitted development limits, need planning permission from the council, and most wraparounds go through a planning application.
Northern Ireland has no Party Wall Act. Shared-wall work relies on agreement with your neighbour and the general law, so we put access and protection arrangements in writing before starting.
Conservation areas, Areas of Outstanding Natural Beauty and listed buildings restrict permitted development in Northern Ireland. At the first visit we measure what is there now and tell you which route fits: permitted development or a planning application.
What are homes in Antrim like to extend?
Antrim has terraces near the centre, semis on the edges and many detached houses and bungalows in the surrounding countryside, where plots are often generous.

FAQ
Wraparound extension questions in Antrim
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
Do you handle building control in Antrim?
Yes. We apply to the council's building control team and hand over the completion certificate.
What roof suits a wraparound?
A flat roof with a lantern, a standing-seam pitched roof or a glazed roof over the side leg. The choice usually follows the first-floor windows above.
How much does a wraparound extension cost in Antrim?
As a guide, £1,910–£3,130 per square metre including VAT for a standard specification. For example, L-shaped, about 22 m² of new floor: about £42,000–£69,000 at that rate. Your written price follows the survey.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
