What is included?

A front garden conversion turns lawn or planting into a parking space: the ground is excavated, a stone sub-base laid, tarmac surfaced on top, and a lowered kerb arranged so a car can cross the pavement legally.

Check the space: length, width and gate posts for a car
Highway authority dropped kerb application guided or handled for you
Lawn, hedge roots and topsoil removed
Sub-base and two tarmac courses, or porous asphalt
Kerbs or blocks as edge restraint
A planted strip kept where it helps drainage and looks

Rules in Hertfordshire

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. Any new or widened crossing over the pavement needs approval from the highway authority (the county or unitary council).
