General Policy 2 requires development to respect local character, amenity, highway safety, and provide adequate parking.

RDG 2019 section 6.3 (Driveways and Front Gardens)
RDG 6.3 guides front garden driveway extensions, requiring net parking increase, under 50% lawn loss, minimal visual impact without shifting public realm boundary, and weighing benefits against amenity loss. The officer applied these tests directly: confirmed net gain, 44% lawn retention, no boundary shift, and benefits outweighing minor garden reduction.
