Planning a driveway extension in Sevenoaks
In Sevenoaks, many front gardens have already been paved once, so new paving often starts with breaking out the old surface.
Planning-sensitive towns and conservation areas are common in the South East, so we check the front-garden rules before quoting.

What you get with our drive extensions service
The hard part is the join. Blocks from the same range can differ in shade from a batch made years ago, and older blocks have weathered, so the survey looks at whether a close match is possible, whether lifting and re-mixing some existing blocks will help, or whether a deliberate border or contrasting panel will look better than a near-miss.
- Old edge restraint taken out and the new paving toothed into the old pattern
- Dig-out and sub-base for the new area
- Check of the existing drive: block range, thickness, levels and condition
- New edging, kerbs or a low retaining edge where the lawn is cut back
- Joint sand, compaction and a clean-down of the old section
Before we price your driveway extension
- Where an electric vehicle charger cable might run
- Edges against lawns, beds, walls and neighbours
- Existing manhole and inspection covers, and whether to recess them
- Block range, thickness, colour and pattern to suit the house
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
Planning and kerb rules in Sevenoaks
Sevenoaks is in England, so these rules apply:
In England, paving in front of the house that covers more than 5 m² needs planning permission unless it is permeable or drains to a lawn, border or soakaway inside your boundary. Permeable block paving, or standard blocks laid to fall onto a planted strip, avoid the need for permission in most cases.
Flats and maisonettes, listed buildings, and homes covered by an Article 4 direction can have tighter rules, and conservation areas, National Parks and National Landscapes restrict some permitted development.
A dropped kerb needs your local highway authority's approval (usually the county, unitary, metropolitan or London borough council), and a new access onto an A, B or C classified road also needs planning permission.
General guidance, not legal advice. Your survey confirms what applies to your home. See the planning guide.
