Permeable block paving in Sevenoaks: the local picture
In Sevenoaks, many front gardens have already been paved once, so new paving often starts with breaking out the old surface.
Chalk, clay and sandy ground all occur across the South East, so the dig and sub-base depth are set on the survey rather than assumed.
How much does a permeable block drive cost in Sevenoaks?
In the South East, a permeable block drive usually costs £115–£185 per m² including VAT. For a 50 m² drive, that is roughly £5,650–£9,200. Your exact price depends on what the survey or your photos show, and is fixed in writing before anything is booked.

What is included?
Permeable block paving is block paving built so that rainwater drains down through the joints into a deep, open-graded stone sub-base, where it is stored and soaks away slowly into the ground or is piped off. The blocks have small spacers or wider joints filled with fine grit instead of sand.
- Grit laying course and permeable blocks with grit-filled joints
- Ground check: how well the soil drains and how high the water table sits
- Edge restraints and any overflow or outlet the design needs
- Deeper dig-out for the open-graded sub-base
- Geotextile layer where the design needs one
What we check on a Sevenoaks survey
- Whether front-garden planning rules apply
- Edges against lawns, beds, walls and neighbours
- Access for a mini-digger, skip or grab lorry
- Steps, thresholds and door heights
- Ground conditions under the old surface and how deep the sub-base must be
Rules for front drives 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.
