What to know before a driveway extension in Belfast
Belfast has everything from short terrace frontages to wide drives on newer estates, so the survey sets the layout and the dig.
Dropped kerbs in Northern Ireland go through DfI Roads, so we build that timing into the plan for new drives.
How much does a driveway extension cost in Belfast?
For Belfast, our guide is £85–£145 per m² including VAT, so a 15 m² extension is likely to be £1,450–£2,450. 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?
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.
- Dig-out and sub-base for the new area
- Check of the existing drive: block range, thickness, levels and condition
- 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
What we check on a Belfast survey
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
- Where an electric vehicle charger cable might run
- The kerb: is it already dropped, and is it wide enough?
- Whether front-garden planning rules apply
- Where rain will go: falls, lawn, border, channel or soakaway
Do you need permission in Belfast?
Belfast is in Northern Ireland, so these rules apply:
In Northern Ireland, a hard surface between the front of the house and the road that covers or replaces more than 5 m² must be porous or permeable, or drain to a permeable area within the property, to be permitted development.
Hard surfaces within the grounds of a listed building need listed building consent. Planning is handled by your district council, so check with its planning office if you are unsure.
Dropped kerbs in Northern Ireland are approved by DfI Roads (the Department for Infrastructure), not the council; check planning separately with the council.
General guidance, not legal advice. Your survey confirms what applies to your home. See the planning guide.
