Block paved driveway extensions in Caerphilly: the local picture
In Caerphilly, many front gardens have already been paved once, so new paving often starts with breaking out the old surface.
Hilly streets in much of Wales mean many drives slope, which shapes the falls, the edging and the water route.

What is included?
The hard part is the join. Blocks from the same range can differ in shade from a batch made years ago, and older blocks have weathered, so the survey looks at whether a close match is possible, whether lifting and re-mixing some existing blocks will help, or whether a deliberate border or contrasting panel will look better than a near-miss.
- Joint sand, compaction and a clean-down of the old section
- New edging, kerbs or a low retaining edge where the lawn is cut back
- Old edge restraint taken out and the new paving toothed into the old pattern
- Dig-out and sub-base for the new area
- Check of the existing drive: block range, thickness, levels and condition

- Access for a mini-digger, skip or grab lorry
- Block range, thickness, colour and pattern to suit the house
- Existing manhole and inspection covers, and whether to recess them
- 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.
