What to know before a permeable block drive in Hemel Hempstead
Across Hemel Hempstead, front gardens range from narrow terrace plots to broad modern drives, and the best block, pattern and drainage choice changes with them.
Flat ground across much of the East means falls have to be built in carefully so water does not sit on the drive.

What you get with our permeable paving service
Permeable block paving is block paving built so that rainwater drains down through the joints into a deep, open-graded stone sub-base, where it is stored and soaks away slowly into the ground or is piped off. The blocks have small spacers or wider joints filled with fine grit instead of sand.
- Deeper dig-out for the open-graded sub-base
- 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
- Edge restraints and any overflow or outlet the design needs
Before we price your permeable block drive
- Existing manhole and inspection covers, and whether to recess them
- The kerb: is it already dropped, and is it wide enough?
- Where an electric vehicle charger cable might run
- Ground conditions under the old surface and how deep the sub-base must be
- Steps, thresholds and door heights
Do you need permission in Hemel Hempstead?
Hemel Hempstead 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.
