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.
The South West is wetter than the east of England, so falls and drainage are planned before the pattern is chosen.
- New edging, kerbs or a low retaining edge where the lawn is cut back
- Dig-out and sub-base for the new area
- 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
What the survey covers
- Edges against lawns, beds, walls and neighbours
- Where rain will go: falls, lawn, border, channel or soakaway
- The kerb: is it already dropped, and is it wide enough?
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
- Existing manhole and inspection covers, and whether to recess them
Rules for front drives in Somerset
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.
