Do I need permission in Harrow?

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 is included in a new tarmac driveway?

A new tarmac driveway is built from the ground up: the old surface and soil are dug out, a compacted stone sub-base is laid, then a hot binder course and a finer surface course are spread and rolled, and the edges are held by kerbs or blocks.

Break out and remove the old surface and spoil
Geotextile membrane where the ground is soft or clay
MOT Type 1 sub-base laid and compacted in layers, about 150 mm
Surface course (AC 6 dense), about 20–30 mm, laid hot and rolled
Falls set so water runs to a channel, gully or soft landscaping
