What to know before a permeable block drive in Purley
Across Purley, front gardens range from narrow terrace plots to broad modern drives, and the best block, pattern and drainage choice changes with them.
Front gardens in much of London are short, so parking depth and the dropped kerb usually decide whether a drive is possible.

What is included?
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
- 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
- Grit laying course and permeable blocks with grit-filled joints
- Edge restraints and any overflow or outlet the design needs
What the survey covers
- Ground conditions under the old surface and how deep the sub-base must be
- Steps, thresholds and door heights
- Edges against lawns, beds, walls and neighbours
- Access for a mini-digger, skip or grab lorry
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
Planning and kerb rules in Purley
Purley 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.
