Why these rules

Grey belt is green belt land that does not strongly contribute to purposes (a), (b) or (d) of the green belt: checking sprawl, keeping towns apart and the setting of historic towns (NPPF, August 2026, glossary and GB2). Whether land is grey belt needs the council's assessment against those purposes (Annex E); Plota finds the candidates.

National policy (NPPF, August 2026, GB7(g)) allows development on grey belt land that does not undermine the remaining green belt, where there is an evidenced unmet need and the location is sustainable.

National parks and the Broads are left out: national policy refuses major development there other than in exceptional circumstances and limits the scale of the rest (NPPF, August 2026, N4); set National park to Any under Constraints to include them. Woodland is left out.
