DM18 — Protection of Open Space.
How Harrow actually applies DM18: who leans on it, where it bites hardest, and how often it's invoked. The policy text is the rule; this is the behaviour.
DM18 is a published Harrow planning policy. This page records where it appears in the council's published planning decisions.
Cited under: Harrow Local Plan (adopted)
Policy DM18 protects open space in Harrow by not releasing land for development, supporting ancillary development where it doesn't harm the open space, and allowing reconfiguration if it enhances the open space without causing environmental harm. This applies to land identified as open space on the Harrow Policies Map, including parks, gardens, play areas, and natural conservation sites. The council will resist development that harms the open space and support reconfiguration that improves its capacity, quality, and accessibility.

From Planning Inspectorate decision letters that cite DM18. Dismissed = the council's refusal stood, the policy held; allowed = overturned. Too few decisive appeals for a rate — the counts are the record. The tighter join — this borough's own refusals citing DM18 traced to their specific appeals — is still to come.
