What to know before a driveway extension in Chesham
Around Chesham, plots are often larger and drives longer, so edging, falls and the route the water takes need planning.
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.

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.
- Matching options: same range, re-mixing old and new, or a planned contrast
- 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
What the survey covers
- Ground conditions under the old surface and how deep the sub-base must be
- The kerb: is it already dropped, and is it wide enough?
- Whether front-garden planning rules apply
- Access for a mini-digger, skip or grab lorry
- Where rain will go: falls, lawn, border, channel or soakaway
Rules for front drives in Chesham
Chesham 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.
