How to use BelfastBuild well.
A little detail goes a long way. The better the proposal summary, the more useful the screening result will be.
Describe the proposal clearly
Include the type of development, number of units or storeys, parking changes, extensions, access changes and any nearby sensitive context such as a conservation area.
Review the flagged policies
Use the conflict summaries and citations to understand which planning clauses may affect the proposal and where those clauses come from.
Refine before you submit
Treat the remediation guidance as a pre-application checklist to strengthen drawings, parking layouts, density choices and design rationale before moving forward.

A postcode grounds the spatial lookup; a short description lets the RAG pipeline surface the right clauses from the indexed policy set.
