What to know before a driveway extension in Brentwood
Brentwood is a sizeable town with a mix of semis, terraces and newer estates, and many drives here were first laid decades ago.
Flat ground across much of the East means falls have to be built in carefully so water does not sit on the drive.
How much does a driveway extension cost in Brentwood?
Expect driveway extensions in Brentwood to come in at around £95–£160 per m², including VAT at 20%. As an example, a 15 m² extension usually comes to between £1,650 and £2,700.

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.
- Check of the existing drive: block range, thickness, levels and condition
- Dig-out and sub-base for the new area
- 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
- Matching options: same range, re-mixing old and new, or a planned contrast
What the survey covers
- Trees and roots near the drive
- Whether front-garden planning rules apply
- 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
- Where an electric vehicle charger cable might run
Do you need permission in Brentwood?
Brentwood 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.
