Block paved driveway extensions in Rhiwbina: the local picture
In and around Rhiwbina, village-style frontages sit alongside newer cul-de-sacs, so the right block often depends on the age of the house.
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.
How much does a driveway extension cost in Rhiwbina?
For Rhiwbina, our guide is £85–£140 per m² including VAT, so a 15 m² extension is likely to be £1,450–£2,400. Smaller jobs cost more per square metre because set-up and waste costs do not shrink with the area.

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.
- Check of the existing drive: block range, thickness, levels and condition
- Old edge restraint taken out and the new paving toothed into the old pattern
- New edging, kerbs or a low retaining edge where the lawn is cut back
- Matching options: same range, re-mixing old and new, or a planned contrast
- Joint sand, compaction and a clean-down of the old section
What we check on a Rhiwbina survey
- Whether front-garden planning rules apply
- Ground conditions under the old surface and how deep the sub-base must be
- Where rain will go: falls, lawn, border, channel or soakaway
- Edges against lawns, beds, walls and neighbours
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
Rules for front drives in Rhiwbina
Rhiwbina 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.
