Wraparound extension in Larne
Wraparound extension in Larne: an L-shaped extension that fills the side return and runs across the back. We measure the house, show you what the rules allow, price it in writing and build it.
Larne is covered from our County Antrim round, including BT40. 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 Larne?
Here is how the rules in Northern Ireland apply to a wraparound extension in Larne.
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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Larne like to extend?
Larne has terraces near the centre, semis on the edges and many detached houses and bungalows in the surrounding countryside, where plots are often generous.
How a wraparound extension in Larne comes together
Survey visit
We visit free of charge, measure up, check access, drainage and neighbours' extensions, and note what you want the room to do.
Options and costs
We draw layout options and price each one, so the budget shapes the design rather than surprising you later.
Planning and regulations
We take the design through the right planning route, then produce the construction drawings and engineer's calculations for council building control.
Written price, then build
Once the design and approvals are in place, you get a fixed written price and programme, and we build through to sign-off.
