What to know before a driveway extension in St Albans
St Albans has a big mix of housing, from older terraces near the centre to newer estates further out, so no two drives here start from the same ground.
Clay soils are common in parts of the East of England, so drainage and sub-base depth get extra attention.

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.
- Joint sand, compaction and a clean-down of the old section
- Old edge restraint taken out and the new paving toothed into the old pattern
- New edging, kerbs or a low retaining edge where the lawn is cut back
- Matching options: same range, re-mixing old and new, or a planned contrast
- Dig-out and sub-base for the new area
Before we price your driveway extension
- Trees and roots near the drive
- Whether front-garden planning rules apply
- Where an electric vehicle charger cable might run
- Ground conditions under the old surface and how deep the sub-base must be
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
Planning and kerb rules in St Albans
St Albans 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.
