What to know before a driveway extension in Darwen
In Darwen, many front gardens have already been paved once, so new paving often starts with breaking out the old surface.
Terraced streets across the North West often have very short frontages, so we check parking depth before quoting a conversion.
How much does a driveway extension cost in Darwen?
For Darwen, our guide is £90–£150 per m² including VAT, so a 15 m² extension is likely to be £1,550–£2,600. Smaller jobs cost more per square metre because set-up and waste costs do not shrink with the area.

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.
- Joint sand, compaction and a clean-down of the old section
- Check of the existing drive: block range, thickness, levels and condition
- 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
What the survey covers
- Ground conditions under the old surface and how deep the sub-base must be
- The kerb: is it already dropped, and is it wide enough?
- Existing manhole and inspection covers, and whether to recess them
- Block range, thickness, colour and pattern to suit the house
- Access for a mini-digger, skip or grab lorry
Rules for front drives in Darwen
Darwen 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.
