Paving a Front Garden and Dropped Kerbs: The Planning Rules
Paving a front garden for parking can need planning permission — but a permeable surface usually avoids it, whatever the size. This guide explains the 5 square metre rule, the drainage reason behind it, and the separate consent a dropped kerb requires.
The 5 square metre rule
Paving over a front garden is permitted development — needing no planning permission — as long as the surface lets water drain naturally. Planning permission is only required where more than 5 square metres of the front garden is covered with a traditional, impermeable surface that does not allow rainwater to soak away or run to a permeable area. Below that area, or with a surface that drains, it is not caught.
Why permeable surfaces avoid it
The rule exists because hard, impermeable front gardens push rainwater into the drains and contribute to surface-water flooding. The simplest way to stay within permitted development, at any size, is therefore to use a permeable or porous surface — gravel, permeable block paving or porous asphalt — or to direct the rainwater to a lawn or planted border where it can drain naturally. That keeps the driveway outside planning control and is better for the street’s drainage.
Dropped kerbs are separate
Creating a new vehicle access across the footway needs its own permission from the council as highway authority — a dropped kerb, or vehicle crossover, application — which is separate from the planning position on the paving itself. The footway may need strengthening to take vehicles, and where the access is onto a classified road, planning permission for the access can be required as well. It is worth resolving both before laying anything.
Walls, railings and conservation areas
Front boundary treatments have their own limits: a wall, fence or gate next to a highway used by vehicles is generally permitted development only up to 1 metre high (up to 2 metres elsewhere), and removing or altering a front boundary wall can need permission — particularly in a conservation area, where the character of front gardens and boundaries is protected and permitted development rights may be restricted. In much of prime London the front garden is part of the streetscape the planners are trying to preserve, so it is worth checking before changing it.
