FAQ

Frequently Asked Questions

Do I need planning permission for a house extension in Ireland?

Under updated Irish planning regulations effective July 2026, rear house extensions up to 45m² are exempt from planning permission, up from the previous 40m² limit. Standard boundary, height, and open-space conditions apply. We confirm compliance at your initial site survey at no cost.
A standard single-storey rear extension takes 10–16 weeks from commencement on site, depending on size and specification. We issue a written programme before starting and update it regularly throughout the build.
A well-specified extension typically ranges from €1,500–€2,500 per m² depending on structural complexity, glazing specification, and finish level. Beaufort provides fixed-price, itemised quotes — so you know the number before we start.
Yes. We build house extensions throughout Dublin City and County, including Dublin South (Terenure, Rathfarnham, D6, D14), Dublin North (Swords, Malahide, D9), and Dublin West (Blanchardstown, Lucan, D15).
We can advise on planning requirements and liaise with your architect where needed. Many projects fall within current exemption limits — we will confirm this at your site survey.
