Planning a driveway extension in Blackwood
Blackwood is a smaller town, and many of its homes have more frontage to work with than city houses, which leaves room for borders and planting.
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 does a driveway extension involve?
A driveway extension adds paving to an existing drive, usually to fit a second car by taking in part of the front lawn, or to lengthen a drive towards the house or garage. The new section is built on its own sub-base and tied into the old paving so the two act as one surface.
- Dig-out and sub-base for the new area
- Matching options: same range, re-mixing old and new, or a planned contrast
- Joint sand, compaction and a clean-down of the old section
- Check of the existing drive: block range, thickness, levels and condition
- New edging, kerbs or a low retaining edge where the lawn is cut back
What the survey covers
- Access for a mini-digger, skip or grab lorry
- 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
- Block range, thickness, colour and pattern to suit the house
Planning and kerb rules in Blackwood
Blackwood 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.
