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.
Dropped kerbs in Northern Ireland go through DfI Roads, so we build that timing into the plan for new drives.
- Check of the existing drive: block range, thickness, levels and condition
- Matching options: same range, re-mixing old and new, or a planned contrast
- Joint sand, compaction and a clean-down of the old section
- Old edge restraint taken out and the new paving toothed into the old pattern
- New edging, kerbs or a low retaining edge where the lawn is cut back
What the survey covers
- Block range, thickness, colour and pattern to suit the house
- Ground conditions under the old surface and how deep the sub-base must be
- Whether front-garden planning rules apply
- Where an electric vehicle charger cable might run
- Access for a mini-digger, skip or grab lorry
Rules for front drives in County Down
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.
