Question 1

Can I widen my driveway?

Accepted Answer

Usually yes, with two things to check. The same front-garden planning rule applies to the new impermeable area, so more than five square metres needs permission unless it drains permeably. And if the widening reaches the highway, the dropped kerb has to be extended too — a separate consent from Cheshire East, on its own timetable. The technical challenge with widening is the join. The new section has to marry into something built years ago to an unknown specification, and the joint between the two is where a widened drive fails — two different build-ups, settling at different rates, with a straight line for water to get into. Done properly, the new section is dug to its own full depth, the existing edge is cut back to something solid, and the surface is laid across the joint rather than butted up to it. The planning position catches people out because they think of it as a small job. The five square metre threshold applies to the impermeable area you are creating, so extending an existing solid drive by more than that puts you in the same position as laying a new one. Building the new section permeable, or draining it to a lawn, border or soakaway, keeps it inside permitted development. Matching is the disappointment worth preparing for. New block paving beside fifteen-year-old block paving will not match, because the old blocks have weathered and the product has usually changed. There are three honest ways round it: shuffle some existing blocks into the new area so the difference is scattered, use a deliberate contrasting border so the change reads as designed, or clean and re-sand the whole drive so at least the dirt matches. Tarmac and resin blend better; imprinted concrete essentially cannot be matched. Excavation near a boundary brings a legal duty. Where the dig goes within three metres of a neighbour's building or structure and below the bottom of its foundations — which a full-depth driveway dig beside a shallow-founded garden wall or garage genuinely can — the Party Wall etc. Act 1996 requires you to serve written notice at least a month before starting. Two things worth designing for rather than discovering. An extra metre of width is worth far more at the entrance, where you swing in off the road, than at the far end by the house — and a small radius at the entrance stops the edge course being clipped every week. And a tree in the way is not simply an obstacle: in a conservation area every tree has six weeks' statutory protection even without a TPO, and root protection can restrict how close a full-depth dig may go even to a tree that is staying.
