What to know before a driveway extension in Blackburn
Across Blackburn, front gardens range from narrow terrace plots to broad modern drives, and the best block, pattern and drainage choice changes with them.
The North West is one of the wetter parts of England, so falls, channel drains and permeable options matter more than usual.

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
- Old edge restraint taken out and the new paving toothed into the old pattern
- Check of the existing drive: block range, thickness, levels and condition
- Matching options: same range, re-mixing old and new, or a planned contrast
- Dig-out and sub-base for the new area
What the survey covers
- Block range, thickness, colour and pattern to suit the house
- Edges against lawns, beds, walls and neighbours
- Trees and roots near the drive
- Where an electric vehicle charger cable might run
- Steps, thresholds and door heights
Do you need permission in Blackburn?
Blackburn 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.
