What to know before a driveway extension in Warminster
Warminster 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.
The South West is wetter than the east of England, so falls and drainage are planned before the pattern is chosen.

What you get with our drive extensions service
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
- 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
- New edging, kerbs or a low retaining edge where the lawn is cut back
What we check on a Warminster survey
- Steps, thresholds and door heights
- Edges against lawns, beds, walls and neighbours
- Block range, thickness, colour and pattern to suit the house
- Where rain will go: falls, lawn, border, channel or soakaway
- Existing manhole and inspection covers, and whether to recess them
Rules for front drives in Warminster
Warminster 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.
