What is included?
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.
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.
- Old edge restraint taken out and the new paving toothed into the old pattern
- Joint sand, compaction and a clean-down of the old section
- Matching options: same range, re-mixing old and new, or a planned contrast
- Dig-out and sub-base for the new area
- New edging, kerbs or a low retaining edge where the lawn is cut back
What the survey covers
- Block range, thickness, colour and pattern to suit the house
- Trees and roots near the drive
- Where an electric vehicle charger cable might run
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
- Whether front-garden planning rules apply
Rules for front drives in Buckinghamshire
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.
