Layer by layer

Do I need permission in Royston?

In England, householder permitted development (Class F of the 2015 General Permitted Development Order) lets you lay a hard surface in front of a house without planning permission if it is porous, or if the rainwater is directed to a permeable area within the property. If the area is more than 5 m² and neither applies, you need permission. Standard dense tarmac is not porous, so a dense tarmac drive needs a lawn, border, channel to a soakaway or other permeable route for its water. A vehicle crossing over the footway is a separate approval, from the highway authority (the county or unitary council).

What we do on a permeable tarmac driveway

A permeable tarmac drive uses porous asphalt, a mix with fewer fine particles so water passes through the gaps, laid on an open-graded stone base that stores the rain and lets it soak into the ground.

Dig out deeper than a standard drive to fit the storage layer
Open-graded permeable sub-base, often Type 3 or 4/20 stone
Porous asphalt binder and surface courses
Overflow to a soakaway or border on slow-draining ground
Edge restraint that does not block the flow
