Planning a driveway extension in Barnet
Homes in Barnet include plenty of semis and detached houses with room for a drive, plus older terraces where parking is tighter.
Many London streets have controlled parking and narrow frontages, so we measure the car space and the crossover before anything else.
How much does a driveway extension cost in Barnet?
In London, a driveway extension usually costs £110–£180 per m² including VAT. For a 15 m² extension, that is roughly £1,850–£3,100. Your exact price depends on what the survey or your photos show, and is fixed in writing before anything is booked.

What is included?
The hard part is the join. Blocks from the same range can differ in shade from a batch made years ago, and older blocks have weathered, so the survey looks at whether a close match is possible, whether lifting and re-mixing some existing blocks will help, or whether a deliberate border or contrasting panel will look better than a near-miss.
- Dig-out and sub-base for the new area
- 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
- New edging, kerbs or a low retaining edge where the lawn is cut back
- Joint sand, compaction and a clean-down of the old section
What we check on a Barnet survey
- Ground conditions under the old surface and how deep the sub-base must be
- Existing manhole and inspection covers, and whether to recess them
- Whether front-garden planning rules apply
- Access for a mini-digger, skip or grab lorry
- Where an electric vehicle charger cable might run
Rules for front drives in Barnet
Barnet 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.
