Wraparound extension in Holywood
Thinking about a wraparound extension in Holywood? An L-shaped extension that fills the side return and runs across the back. Our team handles the drawings, the planning route and the build, and your contract is with one company throughout.
Holywood is covered from our County Down round, including BT18. 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 Holywood?
Planning for a wraparound extension in Holywood follows the Northern Irish householder rules.
Northern Ireland's rules restrict side extensions more than rear ones, so a side infill or wraparound usually needs a planning application to the council as well as building control approval.
There is no Party Wall Act in Northern Ireland; we agree any work affecting a shared wall or boundary directly with the neighbour, in writing.
Conservation areas, Areas of Outstanding Natural Beauty and listed buildings restrict permitted development in Northern Ireland. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Holywood like to extend?
Holywood has terraces near the centre, semis on the edges and many detached houses and bungalows in the surrounding countryside, where plots are often generous.
