In Elson, Permeable & SuDS Driveways is built around low-lying waterside ground on Forton Lake, a tidal inlet of Portsmouth Harbour: a permeable resin, open-jointed block, or gravel-and-grid build-up that lets rainwater drain through rather than run off. Elson’s own driveways are shaped by narrow waterside frontages with real tidal drainage considerations, and waterside exposure on Forton Lake, a tidal inlet of Portsmouth Harbour. That makes it a strong fit for front gardens over 5m² and sites with limited natural fall for surface water — worth knowing 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.
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 Elson
Elson sits on the Gosport peninsula beside Forton Lake, a tidal inlet of Portsmouth Harbour, and that waterside position brings real tidal drainage considerations most streets elsewhere never have to plan for. The older terraced housing typical of the Gosport peninsula sits close to the water, with narrow frontages the norm.
