PlanNavi
PlanNavi helps architects, planning consultants, and property owners navigate Northern Ireland's planning system — before you engage a consultant or submit an application.
Launch the App →PlanNavi works through a guided assessment of your proposal — applying Northern Ireland planning law and policy to give you a clear outcome and practical next steps. It also lets you drop a pin on any site in Northern Ireland to instantly check what planning designations affect it.
All content has been verified against primary NI legislation including the Planning Act (NI) 2011, the GPDO (NI) 2015, PPS 21, and SPPS Edition 2 (December 2025). It is not legal or professional planning advice.
Answer a short series of questions about your site and what you want to do — an extension, a new dwelling, a change of use, agricultural works, and more.
The app applies NI planning law to your answers and tells you whether planning permission is required, which policies apply, and what the council will scrutinise.
Switch to the Site Map tab, drop a pin on your site, and instantly see which planning designations affect it — AONB, ASSI, settlement limits, listed buildings within 150m, and more.
PlanNavi covers the most common planning scenarios in Northern Ireland, all verified against primary legislation.
Drop a pin on any location in Northern Ireland to instantly check planning designations.
