Permeable block paving in Caernarfon: the local picture
Around Caernarfon, plots are often larger and drives longer, so edging, falls and the route the water takes need planning.
Hilly streets in much of Wales mean many drives slope, which shapes the falls, the edging and the water route.

What is included?
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.
- Ground check: how well the soil drains and how high the water table sits
- Deeper dig-out for the open-graded sub-base
- Grit laying course and permeable blocks with grit-filled joints
- Edge restraints and any overflow or outlet the design needs
- Geotextile layer where the design needs one

- Whether front-garden planning rules apply
Planning and kerb rules in Caernarfon
Caernarfon 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.
