What to know before a permeable block drive in Trowbridge
In Trowbridge, many front gardens have already been paved once, so new paving often starts with breaking out the old surface.
Sloping plots are common in the South West, which affects edging, steps and where the water runs.

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.
- 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
- Ground check: how well the soil drains and how high the water table sits
- Edge restraints and any overflow or outlet the design needs
What we check on a Trowbridge survey
- Steps, thresholds and door heights
- Block range, thickness, colour and pattern to suit the house
- Trees and roots near the drive
- Ground conditions under the old surface and how deep the sub-base must be
- Access for a mini-digger, skip or grab lorry
Rules for front drives in Trowbridge
Trowbridge 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.
