Rules for french doors in Northern Ireland
Northern Ireland sets replacement door limits through Technical Booklet F1 (2022): 1.8 W/m²K. Replacing external doors does not need full plans or a building notice, but the work must still comply; enlarging an opening or other structural change needs building control approval.
Planning: Check with your council planning office before changing the style, material or size of doors, and always for listed buildings, conservation areas and flats.
