PlanNavi
PlanNavi helps architects, planning consultants, and property owners navigate the NI planning system — combining spatial analysis with policy guidance before you engage a consultant or submit an application.
Launch the App →PlanNavi works through a guided assessment of your proposal — applying NI planning policy (PPS 21, SPPS, DCAN standards) to give you a clear outcome and practical strategies. Drop a pin on any site in Northern Ireland to instantly see what designations, constraints, and policy considerations apply.
Content is verified against NI primary legislation and policy — the Planning Act (Northern Ireland) 2011, PPS 21, the SPPS, DCAN guidance, PPS 15, and PAC appeal decisions. The tool covers all major NI planning pathways including rural dwellings, extensions, change of use, heritage, major development, and farm diversification.
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 the planning law and policy of your selected region and tells you whether planning permission is required, which policies apply, and what the relevant authority will scrutinise.
Switch to the Site Map tab, drop a pin on your site, and instantly see which planning designations affect it — National Landscapes, protected areas, settlement limits, listed buildings, and more.
PlanNavi covers the most common NI planning scenarios, verified against the Planning Act (NI) 2011, PPS 21, the SPPS, and DCAN guidance.
