Planning a driveway extension in Cumbernauld
In Cumbernauld, many front gardens have already been paved once, so new paving often starts with breaking out the old surface.
In Scotland, front paving must be porous or drain within the property whatever its size, so drainage is part of every design.
In Scotland block paving is often called monoblock; it is the same thing, and the same rules for the base, edging and drainage apply.

Expect driveway extensions in Cumbernauld to come in at around £90–£150 per m², including VAT at 20%. As an example, a 15 m² extension usually comes to between £1,550 and £2,600.

What you get with our drive extensions service
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.
- Old edge restraint taken out and the new paving toothed into the old pattern
- 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
- Matching options: same range, re-mixing old and new, or a planned contrast
- Dig-out and sub-base for the new area
Before we price your driveway extension
- Trees and roots near the drive
- Access for a mini-digger, skip or grab lorry
- Edges against lawns, beds, walls and neighbours
- Block range, thickness, colour and pattern to suit the house
- Whether front-garden planning rules apply
Rules for front drives in Cumbernauld
Cumbernauld is in Scotland, so these rules apply:
In Scotland, a hard surface between the house and the road is permitted development only if it is porous or drains to a permeable area within the property. There is no 5 m² threshold: the rule applies whatever the size.
Hard surfaces are not permitted development in a conservation area or within the grounds of a listed building, so planning permission is needed there.
A dropped kerb needs consent from your council as roads authority under section 56 of the Roads (Scotland) Act 1984, and planning permission may also be needed depending on the road.
General guidance, not legal advice. Your survey confirms what applies to your home. See the planning guide.
