House Extensions in Maidstone
Serving Maidstone & surrounding areas
Maidstone extensions span the widest stock in the borough — interwar semis at Allington and Bearsted, Victorian terraces in the town centre, and substantial detacheds at Loose and Boxley.

House Extensions for Maidstone homes
Why Maidstone house extensions briefs are different
We commission an early soil report on most Maidstone extensions because chalk and clay alternate dramatically across the borough — that report often saves significant money on foundation design later.
Maidstone's stock runs from Allington and Bearsted's interwar semis to large detached homes around Loose and Boxley, plus dense Victorian terracing in the town centre.
Local considerations
Maidstone Borough Council is generally efficient, but the South East area (around Loose and Tovil) sits in an AONB with stricter design controls.
Chalk and clay alternating across the borough means an early soil report often saves significant money on foundation design — we typically commission one with our quote.
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 Maidstone 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 rear kitchen extension to a Bearsted semi last spring, with strip footings on chalk subsoil and matching brick to the existing.

FAQs
House Extensions in Maidstone — frequently asked
Why is a soil report worth it?
Because chalk and clay subsoils need very different foundation designs — a report identifies which you have early.
Do I need planning?
Most rear extensions on Maidstone semis fit permitted development; the town-centre conservation areas 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.
Which villages near Maidstone do you cover?
Loose, Boxley, Bearsted, Marden, Staplehurst and Headcorn among others, across the ME14 to ME17 and TN12 postcodes.
Do you charge a call-out fee for site visits in Maidstone?
No — first site visits and written quotes in Maidstone are free and carry no obligation. Quotes are typically delivered within 5 working days of the visit.
