Permeable block paving in Barnet: the local picture
In Barnet, many front gardens have already been paved once, so new paving often starts with breaking out the old surface.
Front gardens in much of London are short, so parking depth and the dropped kerb usually decide whether a drive is possible.
How much does a permeable block drive cost in Barnet?
For Barnet, our guide is £125–£205 per m² including VAT, so a 50 m² drive is likely to be £6,300–£10,200. Smaller jobs cost more per square metre because set-up and waste costs do not shrink with the area.

What does a permeable block drive involve?
Permeable block paving is block paving built so that rainwater drains down through the joints into a deep, open-graded stone sub-base, where it is stored and soaks away slowly into the ground or is piped off. The blocks have small spacers or wider joints filled with fine grit instead of sand.
- Edge restraints and any overflow or outlet the design needs
- Deeper dig-out for the open-graded sub-base
- Open-graded crushed stone (no fines) laid and compacted in layers
- Geotextile layer where the design needs one
- Grit laying course and permeable blocks with grit-filled joints
Before we price your permeable block drive
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
- Whether front-garden planning rules apply
- Where an electric vehicle charger cable might run
- Block range, thickness, colour and pattern to suit the house
- Access for a mini-digger, skip or grab lorry
Do you need permission in Barnet?
Barnet 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.
