Planning and kerb rules for Swanley
In England, a new hard surface over 5 m² in front of a house needs planning permission unless it is porous or drains to a lawn, border or soakaway within the property. If the job needs a dropped kerb, the highway authority (the county or unitary council) approves it before any work on the footway.
