Planning rules that apply in Bangor, County Down
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.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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.
