Permeable paving in your front garden is permitted development — no planning permission needed. Here’s what counts as permeable, which products qualify, and what the drainage rules mean in practice.
No. Permeable paving in the front garden is permitted development under Part 1 Class F of the GPDO 2015. You do not need to apply for planning permission as long as the surface allows water to drain through it (or directs run-off to a lawn or border within your property).
Permeable paving: no planning permission. Non-permeable paving over 5m² in front garden: planning permission required. Permeable paving in rear garden: no planning permission regardless.
A permeable surface allows rainwater to pass through it and soak into the ground below. An alternative is one that channels run-off to a permeable area within your property — such as a lawn, flower border, or soakaway.
| Surface Type | Permeable? | Notes |
|---|---|---|
| Loose gravel / shingle | ✅ Yes | Classic, low-cost, reliably permeable. |
| Permeable block paving (open jointed) | ✅ Yes | Blocks with gaps filled with gravel. |
| Resin-bound gravel | ✅ Yes | Porous surface, smooth finish, very popular. |
| Grass reinforcement mesh | ✅ Yes | Plastic grid filled with grass or gravel. |
| Porous asphalt / concrete | ✅ Yes | Specially formulated. Less common but effective. |
| Standard block paving (filled joints) | ❌ No | Joints filled with sand/mortar make it impermeable. |
| Standard tarmac / asphalt | ❌ No | Impermeable unless porous variant specified. |
| Standard concrete | ❌ No | Impermeable unless porous variant specified. |
| Resin-bonded gravel | ❌ No | Surface chips on non-porous resin base — impermeable. |
Resin-bound: aggregate fully coated in resin, porous matrix, water passes through. Permitted development. Resin-bonded: aggregate chips on non-porous resin base, water runs off. Not permitted development over 5m² in front garden.
Building regulations do not generally apply to simple driveway paving. If you are installing a new drainage connection to the sewer, building regulations may apply. Check with your local building control office if in doubt.
| Surface Type | Cost per m² |
|---|---|
| Loose gravel | £15 – £40 |
| Permeable block paving | £60 – £100 |
| Resin-bound gravel | £50 – £120 |
| Grass reinforcement mesh | £20 – £50 |
| Porous asphalt | £40 – £80 |
