Bangor, County Down
Wraparound extension in Bangor
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 Bangor and the surrounding area, with one contract from the first survey to building control sign-off.
Bangor is covered from our County Down round, including BT19 and BT20. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in County Down where a side return alone would leave the room too narrow.

Do you need planning permission for a wraparound extension in Bangor?
Here is how the rules in Northern Ireland apply to a wraparound extension in Bangor.
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 Bangor like to extend?
Bangor has terraces near the centre, semis on the edges and many detached houses and bungalows in the surrounding countryside, where plots are often generous.
