What to know before a driveway extension in Finchley
Finchley has a big mix of housing, from older terraces near the centre to newer estates further out, so no two drives here start from the same ground.
Many London streets have controlled parking and narrow frontages, so we measure the car space and the crossover before anything else.

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.
- 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
- Old edge restraint taken out and the new paving toothed into the old pattern
- Dig-out and sub-base for the new area
- Matching options: same range, re-mixing old and new, or a planned contrast
Before we price your driveway extension
- Block range, thickness, colour and pattern to suit the house
- Trees and roots near the drive
- Where rain will go: falls, lawn, border, channel or soakaway
- Whether front-garden planning rules apply
- Where an electric vehicle charger cable might run
Planning and kerb rules in Finchley
Finchley 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.
