Block paved driveway extensions in Harpenden: the local picture
Harpenden is a sizeable town with a mix of semis, terraces and newer estates, and many drives here were first laid decades ago.
Flat ground across much of the East means falls have to be built in carefully so water does not sit on the drive.

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.
- Old edge restraint taken out and the new paving toothed into the old pattern
- Check of the existing drive: block range, thickness, levels and condition
- Joint sand, compaction and a clean-down of the old section
- Dig-out and sub-base for the new area
- New edging, kerbs or a low retaining edge where the lawn is cut back
Before we price your driveway extension
- Steps, thresholds and door heights
- Access for a mini-digger, skip or grab lorry
- Whether front-garden planning rules apply
- Trees and roots near the drive
- Where an electric vehicle charger cable might run
Rules for front drives in Harpenden
Harpenden 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.
