House Extensions for Headcorn homes
Why Headcorn house extensions briefs are different
We pay particular attention to ground conditions in Headcorn, because the low ground south of the railway often hits the water table at 1m — piled or raft foundations are routinely needed where strip footings would fail.
Headcorn is a long ribbon village of medieval timber-framed houses, Edwardian station-side terraces and modern infill estates along Forge Lane and Lenham Road.
Local considerations
Maidstone Borough Council handles applications here and tends to be pragmatic, but the conservation area covering the High Street and church is non-negotiable on materials.
Low-lying ground south of the railway can hit the water table at 1m, so we frequently spec piled or raft foundations rather than traditional strip footings.
Extensions are where ground conditions, sightlines and neighbouring rights-of-light decisions cost real money if missed early. We front-load all three before any drawings are firmed up.
What Headcorn clients ask for
Most clients want clarity on fixed cost, end-to-end timeline and how disruptive the kitchen-relocation period will be — we put those in writing on day one.
Recent local project
We delivered a 32m² rear extension to a Headcorn semi off Lenham Road last summer, with raft foundations over a shallow water table.

FAQs
House Extensions in Headcorn — frequently asked
Why are Headcorn foundations sometimes piled?
Because the water table can be very shallow south of the railway — strip footings simply don't perform there.
Do I need planning in Headcorn?
Most rear extensions fit permitted development; the High Street conservation area properties usually need full consent.
What's the largest extension you can build under permitted development?
Up to 4m deep for a detached house and 3m for a semi/terrace (8m and 6m under the larger neighbour-consultation route until 2025). We confirm yours at survey.
Will I need to move out during the extension build?
On most rear extensions you can stay in the house. Phasing the kitchen break-through is where it gets disruptive — we usually move that to week 8–10 once the new envelope is dry.
How long is the wait to start a project in Headcorn?
Lead times in Headcorn vary by season. Joinery and smaller refurb work typically starts within 4–6 weeks; full extensions and renovations are usually 2–4 months out.
