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.
- Joint sand, compaction and a clean-down of the old section
- 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
- Dig-out and sub-base for the new area
- Matching options: same range, re-mixing old and new, or a planned contrast
What we check on a Milton Keynes survey
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
- Ground conditions under the old surface and how deep the sub-base must be
- Where an electric vehicle charger cable might run
- Block range, thickness, colour and pattern to suit the house
- Existing manhole and inspection covers, and whether to recess them
Planning and kerb rules in Milton Keynes
Milton Keynes is in England, so these rules apply:
In England, paving in front of the house that covers more than 5 m² needs planning permission unless it is permeable or drains to a lawn, border or soakaway inside your boundary. Permeable block paving, or standard blocks laid to fall onto a planted strip, avoid the need for permission in most cases.
Flats and maisonettes, listed buildings, and homes covered by an Article 4 direction can have tighter rules, and conservation areas, National Parks and National Landscapes restrict some permitted development.
A dropped kerb needs your local highway authority's approval (usually the county, unitary, metropolitan or London borough council), and a new access onto an A, B or C classified road also needs planning permission.
General guidance, not legal advice. Your survey confirms what applies to your home. See the planning guide.
