Planning a driveway extension in Trowbridge
Trowbridge is a sizeable town with a mix of semis, terraces and newer estates, and many drives here were first laid decades ago.
The South West is wetter than the east of England, so falls and drainage are planned before the pattern is chosen.
How much does a driveway extension cost in Trowbridge?
In the South West, a driveway extension usually costs £90–£150 per m² including VAT. For a 15 m² extension, that is roughly £1,550–£2,600. Your exact price depends on what the survey or your photos show, and is fixed in writing before anything is booked.

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.
- Check of the existing drive: block range, thickness, levels and condition
- 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
- Dig-out and sub-base for the new area
- New edging, kerbs or a low retaining edge where the lawn is cut back
What the survey covers
- Edges against lawns, beds, walls and neighbours
- Whether front-garden planning rules apply
- Block range, thickness, colour and pattern to suit the house
- Trees and roots near the drive
- Where an electric vehicle charger cable might run
Planning and kerb rules in Trowbridge
Trowbridge 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.
