Planning a driveway extension in Monmouth
Around Monmouth, 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.
How much does a driveway extension cost in Monmouth?
For Monmouth, 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.
- Matching options: same range, re-mixing old and new, or a planned contrast
- Old edge restraint taken out and the new paving toothed into the old pattern
- Dig-out and sub-base for the new area
- New edging, kerbs or a low retaining edge where the lawn is cut back
- Joint sand, compaction and a clean-down of the old section
What we check on a Monmouth survey
- Steps, thresholds and door heights
- Ground conditions under the old surface and how deep the sub-base must be
- Trees and roots near the drive
- Where an electric vehicle charger cable might run
- Existing manhole and inspection covers, and whether to recess them
Do you need permission in Monmouth?
Monmouth 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.
