What to know before a permeable block drive in Northampton
Across Northampton, front gardens range from narrow terrace plots to broad modern drives, and the best block, pattern and drainage choice changes with them.
Block drives laid twenty or thirty years ago are often ready for re-laying rather than replacing, because sound blocks outlast a weak base.

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.
- Ground check: how well the soil drains and how high the water table sits
- Grit laying course and permeable blocks with grit-filled joints
- Open-graded crushed stone (no fines) laid and compacted in layers
- Deeper dig-out for the open-graded sub-base
- Geotextile layer where the design needs one
What we check on a Northampton survey
- Ground conditions under the old surface and how deep the sub-base must be
- Edges against lawns, beds, walls and neighbours
- Steps, thresholds and door heights
- Access for a mini-digger, skip or grab lorry
- Existing manhole and inspection covers, and whether to recess them
Planning and kerb rules in Northampton
Northampton 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.
