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.
Sloping plots are common in the South West, which affects edging, steps and where the water runs.
- New edging, kerbs or a low retaining edge where the lawn is cut back
- Check of the existing drive: block range, thickness, levels and condition
- Matching options: same range, re-mixing old and new, or a planned contrast
- Joint sand, compaction and a clean-down of the old section
- Old edge restraint taken out and the new paving toothed into the old pattern
What the survey covers
- Trees and roots near the drive
- The kerb: is it already dropped, and is it wide enough?
- Ground conditions under the old surface and how deep the sub-base must be
- Steps, thresholds and door heights
- Whether front-garden planning rules apply
Rules for front drives in Devon
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.
