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.
Sloping plots are common in the South West, which affects edging, steps and where the water runs.
- Edge restraints and any overflow or outlet the design needs
- Deeper dig-out for the open-graded sub-base
- Geotextile layer where the design needs one
- 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
- Steps, thresholds and door heights
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
- Ground conditions under the old surface and how deep the sub-base must be
- Where rain will go: falls, lawn, border, channel or soakaway
- Access for a mini-digger, skip or grab lorry
Rules for front drives in Devon
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.
