What does a permeable block drive involve?
It is the straightforward way to pave a front garden without sending rain into the road, which matters because in England a non-permeable front surface over 5 m² that does not drain to a permeable area within the property needs planning permission, and in Wales any new front surface must be permeable or drain within the property. The build is different from a standard drive from the ground up, so it has to be designed as permeable rather than just using different blocks.
Hilly streets in much of Wales mean many drives slope, which shapes the falls, the edging and the water route.
- Geotextile layer where the design needs one
- Grit laying course and permeable blocks with grit-filled joints
- Edge restraints and any overflow or outlet the design needs
- Deeper dig-out for the open-graded sub-base
- Open-graded crushed stone (no fines) laid and compacted in layers
What the survey covers
- The kerb: is it already dropped, and is it wide enough?
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
- Access for a mini-digger, skip or grab lorry
- Block range, thickness, colour and pattern to suit the house
- Ground conditions under the old surface and how deep the sub-base must be
Rules for front drives in South Glamorgan
In Wales, any new or replacement hard surface at the front of a house should be permeable or drain to a permeable area within the property to avoid needing planning permission. Unlike England, there is no 5 m² allowance for new paving; only repairs of up to 5 m² of existing surface are exempt.
Since January 2019, construction work covering 100 m² or more with drainage implications, including drives and patios, needs approval from the local SuDS Approving Body (SAB) before work starts, even where planning permission is not needed.
A dropped kerb needs your council's approval as highway authority, and a new access onto a classified road needs planning permission.
General guidance, not legal advice. Your survey confirms what applies to your home. See the planning guide.
