What is included?
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.
- Joint sand, compaction and a clean-down of the old section
- Matching options: same range, re-mixing old and new, or a planned contrast
- Old edge restraint taken out and the new paving toothed into the old pattern
- Check of the existing drive: block range, thickness, levels and condition
- Dig-out and sub-base for the new area
What the survey covers
- Steps, thresholds and door heights
- Edges against lawns, beds, walls and neighbours
- Block range, thickness, colour and pattern to suit the house
- Ground conditions under the old surface and how deep the sub-base must be
- The kerb: is it already dropped, and is it wide enough?
Rules for front drives in County Antrim
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.
