What to know before a permeable block drive in Harpenden
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?
It is the straightforward way to pave a front garden without sending rain into the road, which matters because in England a non-permeable front surface over 5 m² that does not drain to a permeable area within the property needs planning permission, and in Wales any new front surface must be permeable or drain within the property. The build is different from a standard drive from the ground up, so it has to be designed as permeable rather than just using different blocks.
- Deeper dig-out for the open-graded sub-base
- Edge restraints and any overflow or outlet the design needs
- Grit laying course and permeable blocks with grit-filled joints
- Open-graded crushed stone (no fines) laid and compacted in layers
- Ground check: how well the soil drains and how high the water table sits
What the survey covers
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
- Trees and roots near the drive
- Block range, thickness, colour and pattern to suit the house
- Access for a mini-digger, skip or grab lorry
- Ground conditions under the old surface and how deep the sub-base must be
Do you need permission 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.
