What does a driveway extension involve?
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.
Hilly streets in much of Wales mean many drives slope, which shapes the falls, the edging and the water route.
- Check of the existing drive: block range, thickness, levels and condition
- Matching options: same range, re-mixing old and new, or a planned contrast
- Dig-out and sub-base for the new area
- 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
What the survey covers
- Existing manhole and inspection covers, and whether to recess them
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
- Trees and roots near the drive
- The kerb: is it already dropped, and is it wide enough?
- Steps, thresholds and door heights
Rules for front drives in Gwynedd
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.
