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.
- Dig-out and sub-base for the new area
- Old edge restraint taken out and the new paving toothed into the old pattern
- Matching options: same range, re-mixing old and new, or a planned contrast
- Check of the existing drive: block range, thickness, levels and condition
- New edging, kerbs or a low retaining edge where the lawn is cut back
What the survey covers
- The kerb: is it already dropped, and is it wide enough?
- Whether front-garden planning rules apply
- Existing manhole and inspection covers, and whether to recess them
- Steps, thresholds and door heights
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
Do you need permission in Castlereagh?
Castlereagh 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.
