What to know before a driveway extension in Farnworth
In Farnworth, many front gardens have already been paved once, so new paving often starts with breaking out the old surface.
The North West is one of the wetter parts of England, so falls, channel drains and permeable options matter more than usual.

What does a driveway extension involve?
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
- Dig-out and sub-base for the new area
- Check of the existing drive: block range, thickness, levels and condition
- Matching options: same range, re-mixing old and new, or a planned contrast
Before we price your driveway extension
- Trees and roots near the drive
- Where an electric vehicle charger cable might run
- Where rain will go: falls, lawn, border, channel or soakaway
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
- Ground conditions under the old surface and how deep the sub-base must be
Planning and kerb rules in Farnworth
Farnworth 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.
