Rules that apply in Ampthill

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. If the job needs a dropped kerb, the highway authority (the county or unitary council) approves it before any work on the footway.
