What to know before a driveway extension in Port Glasgow
Around Port Glasgow, plots are often larger and drives longer, so edging, falls and the route the water takes need planning.
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.

What you get with our drive extensions service
The hard part is the join. Blocks from the same range can differ in shade from a batch made years ago, and older blocks have weathered, so the survey looks at whether a close match is possible, whether lifting and re-mixing some existing blocks will help, or whether a deliberate border or contrasting panel will look better than a near-miss.
- Matching options: same range, re-mixing old and new, or a planned contrast
- Dig-out and sub-base for the new area
- 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
- Old edge restraint taken out and the new paving toothed into the old pattern
What the survey covers
- Where rain will go: falls, lawn, border, channel or soakaway
- The kerb: is it already dropped, and is it wide enough?
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
- Existing manhole and inspection covers, and whether to recess them
- Where an electric vehicle charger cable might run
Rules for front drives in Port Glasgow
Port Glasgow 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.
