What to know before a driveway extension in Bangor, Gwynedd
Bangor, Gwynedd 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.
Hilly streets in much of Wales mean many drives slope, which shapes the falls, the edging and the water route.

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.
- New edging, kerbs or a low retaining edge where the lawn is cut back
- Joint sand, compaction and a clean-down of the old section
- Check of the existing drive: block range, thickness, levels and condition
- Dig-out and sub-base for the new area
- Old edge restraint taken out and the new paving toothed into the old pattern
What the survey covers
- Existing manhole and inspection covers, and whether to recess them
- Edges against lawns, beds, walls and neighbours
- Where an electric vehicle charger cable might run
- The kerb: is it already dropped, and is it wide enough?
- Where rain will go: falls, lawn, border, channel or soakaway
Planning and kerb rules in Bangor, Gwynedd
Bangor, Gwynedd is in Wales, so these rules apply:
In Wales, any new or replacement hard surface at the front of a house should be permeable or drain to a permeable area within the property to avoid needing planning permission. Unlike England, there is no 5 m² allowance for new paving; only repairs of up to 5 m² of existing surface are exempt.
Since January 2019, construction work covering 100 m² or more with drainage implications, including drives and patios, needs approval from the local SuDS Approving Body (SAB) before work starts, even where planning permission is not needed.
A dropped kerb needs your council's approval as highway authority, and a new access onto a classified road needs planning permission.
General guidance, not legal advice. Your survey confirms what applies to your home. See the planning guide.
