Permeable & SuDS Driveways suits Dibden Purlieu well, given mixed housing right on the New Forest boundary; in practice that means a permeable resin, open-jointed block, or gravel-and-grid build-up that lets rainwater drain through rather than run off. What that means on the ground in Dibden Purlieu is naturally free-draining ground that reduces the drainage burden on the surface choice. Where it earns its keep is front gardens over 5m² and sites with limited natural fall for surface water; the honest caveat is that since October 2008 in England, over 5m² of impermeable surfacing draining to the highway generally needs planning permission — a permeable surface generally does not, though this is general guidance, not a guarantee for any specific property. Dibden Purlieu additionally has New Forest-edge planning sensitivity.
About Permeable & SuDS Driveways
Permeable and SuDS (Sustainable Drainage Systems) driveways use a surface and sub-base combination that lets rainwater soak through into the ground or a storage layer beneath, rather than sheeting off the surface toward the highway or a neighbouring property. In practice that means a permeable resin-bound system, block paving laid with open, permeable joints, or a properly built gravel-and-grid system, each sitting over a sub-base designed to hold and disperse water rather than just support weight. This is directly relevant to a genuinely useful planning rule: since October 2008 in England, laying more than 5m² of impermeable hard surfacing in a front garden that drains to the highway requires planning permission, whereas a permeable surface, or one draining to a soakaway or border, generally does not. That is a factual, general planning position — it is not a guarantee that any specific property qualifies, and it does not cover handling or submitting a planning application.
Best suited to: front gardens over 5m², low-lying or flood-plain sites, and anywhere surface water has limited natural fall away from the property
Less suited to: sites where a fully sealed, zero-drainage surface is specifically required for another reason
Ground & property in Dibden Purlieu
Dibden Purlieu sits directly on the New Forest boundary, where the ground is genuinely free-draining sandy gravel rather than the clay or chalk found elsewhere in the catchment. Being right on the Forest edge also brings planning sensitivity that a standard suburban street simply doesn’t have to consider.
