Planning a driveway extension in Barrhead
In and around Barrhead, village-style frontages sit alongside newer cul-de-sacs, so the right block often depends on the age of the house.
Frost and heavy rain test paving in Scotland, so a well-drained sub-base and full joints matter as much as the blocks.
In Scotland block paving is often called monoblock; it is the same thing, and the same rules for the base, edging and drainage apply.

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.
- Old edge restraint taken out and the new paving toothed into the old pattern
- Dig-out and sub-base for the new area
- Matching options: same range, re-mixing old and new, or a planned contrast
- New edging, kerbs or a low retaining edge where the lawn is cut back
- Check of the existing drive: block range, thickness, levels and condition
What the survey covers
- The kerb: is it already dropped, and is it wide enough?
- Block range, thickness, colour and pattern to suit the house
- Trees and roots near the drive
- Steps, thresholds and door heights
- Edges against lawns, beds, walls and neighbours
Rules for front drives in Barrhead
Barrhead 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.
