What to know before a driveway extension in Antrim
Antrim is a smaller town, and many of its homes have more frontage to work with than city houses, which leaves room for borders and planting.
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 Antrim?
For Antrim, 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?
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.
- 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
- Joint sand, compaction and a clean-down of the old section
- 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
- Access for a mini-digger, skip or grab lorry
- Ground conditions under the old surface and how deep the sub-base must be
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
- Steps, thresholds and door heights
- Where rain will go: falls, lawn, border, channel or soakaway
Planning and kerb rules in Antrim
Antrim 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.
