What to know before a driveway extension in Mitcham
Mitcham has everything from short terrace frontages to wide drives on newer estates, so the survey sets the layout and the dig.
Front gardens in much of London are short, so parking depth and the dropped kerb usually decide whether a drive is possible.
How much does a driveway extension cost in Mitcham?
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 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.
- 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
- Matching options: same range, re-mixing old and new, or a planned contrast
- Check of the existing drive: block range, thickness, levels and condition
- Dig-out and sub-base for the new area
What the survey covers
- Edges against lawns, beds, walls and neighbours
- Steps, thresholds and door heights
- Whether front-garden planning rules apply
- Access for a mini-digger, skip or grab lorry
- Trees and roots near the drive
Planning and kerb rules in Mitcham
Mitcham 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.
