Planning a permeable block drive in Caerphilly
In Caerphilly, many front gardens have already been paved once, so new paving often starts with breaking out the old surface.
Wales is wetter than most of England, and new front paving has to be permeable or drain within the property, so drainage is designed in from the start.

What you get with our permeable paving service
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
- Geotextile layer where the design needs one
- Edge restraints and any overflow or outlet the design needs
- Deeper dig-out for the open-graded sub-base
What we check on a Caerphilly survey
- Edges against lawns, beds, walls and neighbours
- Where rain will go: falls, lawn, border, channel or soakaway
- Trees and roots near the drive
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
- Whether front-garden planning rules apply
Rules for front drives in Caerphilly
Caerphilly is in Wales, so these rules apply:
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.
