When a porch extension makes sense
- Busy hallways with no storage
- Homes wanting better kerb appeal
- Front doors that open straight into a living room
Do I need planning permission in Coleraine?
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 Coleraine address depends on its history and any designations, which is why we check it at the first visit.
Northern Ireland has no Party Wall Act. Where work is on or close to a shared boundary, we agree access and protection with your neighbour in writing before work starts.
Building close to a public sewer needs the agreement of NI Water, which we check during design.
Applications are decided by your council, which handles local planning in Northern Ireland.
