What to know before a permeable block drive in Stevenage
Stevenage 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.
Flat ground across much of the East means falls have to be built in carefully so water does not sit on the drive.

What does a permeable block drive involve?
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
- Geotextile layer where the design needs one
- Ground check: how well the soil drains and how high the water table sits
- Open-graded crushed stone (no fines) laid and compacted in layers
- Edge restraints and any overflow or outlet the design needs
What we check on a Stevenage survey
- Block range, thickness, colour and pattern to suit the house
- Edges against lawns, beds, walls and neighbours
- Ground conditions under the old surface and how deep the sub-base must be
- Where rain will go: falls, lawn, border, channel or soakaway
- Existing manhole and inspection covers, and whether to recess them
Planning and kerb rules in Stevenage
Stevenage 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.
