Planning rules that apply in Antrim
In Northern Ireland a small porch is usually permitted development within limits on floor area, height and distance from a road; larger porches need planning permission from the council, and building control rules still apply.
The planning position for a specific Antrim address depends on its history and any designations, which is why we check it at the first visit.
Building close to a public sewer needs the agreement of NI Water, which we check during design.
In Northern Ireland building control is run by the councils under the Building Regulations (Northern Ireland). We submit full plans or a building notice and book the inspections through to completion.
Applications are decided by your council, which handles local planning in Northern Ireland.
