Permeable block paving in Harrow: the local picture
Across Harrow, front gardens range from narrow terrace plots to broad modern drives, and the best block, pattern and drainage choice changes with them.

What you get with our permeable paving service
It is the straightforward way to pave a front garden without sending rain into the road, which matters because in England a non-permeable front surface over 5 m² that does not drain to a permeable area within the property needs planning permission, and in Wales any new front surface must be permeable or drain within the property. The build is different from a standard drive from the ground up, so it has to be designed as permeable rather than just using different blocks.
- Deeper dig-out for the open-graded sub-base
- Edge restraints and any overflow or outlet the design needs
- Ground check: how well the soil drains and how high the water table sits
- Geotextile layer where the design needs one
- Open-graded crushed stone (no fines) laid and compacted in layers
What we check on a Harrow survey
- The kerb: is it already dropped, and is it wide enough?
- Edges against lawns, beds, walls and neighbours
- Access for a mini-digger, skip or grab lorry
- Where an electric vehicle charger cable might run
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
Planning and kerb rules in Harrow
Harrow 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.
