What to know before a replacement block drive in Caernarfon
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 does a replacement block drive involve?
Replacing an old drive with block paving means breaking out the existing tarmac, concrete or gravel, checking what is underneath, and then building a block drive on a sound base. Many older tarmac and concrete drives have cracked, sunk or broken up, which is why this is such a common way into block paving.
- Assessment of the old base: keep, top up or replace
- Break-out of the old surface with waste removal and skip or grab lorry
- New edging, sub-base where needed, and the block drive
- Levels set below the damp-proof course with falls away from the house
- Drainage added where the old drive sent water to the house or road
What the survey covers
- Edges against lawns, beds, walls and neighbours
- Where an electric vehicle charger cable might run
- Where rain will go: falls, lawn, border, channel or soakaway
- Block range, thickness, colour and pattern to suit the house
- Whether front-garden planning rules apply
Rules for front drives 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.
General guidance, not legal advice. Your survey confirms what applies to your home. See the planning guide.
