Block paved driveway extensions in Kempston: the local picture
Around Kempston, plots are often larger and drives longer, so edging, falls and the route the water takes need planning.
Clay soils are common in parts of the East of England, so drainage and sub-base depth get extra attention.

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.
- New edging, kerbs or a low retaining edge where the lawn is cut back
- Joint sand, compaction and a clean-down of the old section
- Check of the existing drive: block range, thickness, levels and condition
- Matching options: same range, re-mixing old and new, or a planned contrast
- Old edge restraint taken out and the new paving toothed into the old pattern
Before we price your driveway extension
- Block range, thickness, colour and pattern to suit the house
- Whether front-garden planning rules apply
- Trees and roots near the drive
- 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)
Do you need permission in Kempston?
Kempston 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.
