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