House extensions in Kent.
We design nothing and hide nothing. You bring the drawings, we build them properly. WS Builders takes on single and double storey extensions across Canterbury and Kent, running the whole job from foundations to final plaster with one small team on site throughout.
Bradley prices every extension personally after a free site visit, and the written quote is itemised so you can see exactly what the money buys. We liaise with Building Control, your architect and your structural engineer as part of the job, not as an extra.

FAQs
Common questions.
How much does a house extension in Kent cost?
It depends on size, groundworks, structural steel and the level of finish, which is why we quote from a free site visit rather than a price list. Every quote is written and itemised, covering costs, materials and timings, so you can compare it line by line with no hidden extras.
How long does a single storey extension normally take?
Most single storey extensions take roughly 8 to 14 weeks on site depending on size, ground conditions and the finish inside. You get an honest timeline in the written quote and regular updates as the job runs.
Can you manage Building Control and structural engineers?
Yes. We liaise with Building Control, your architect and your structural engineer as a standard part of every extension, and we book the inspections at the right stages.
Do I need planning permission for an extension in Kent?
Many single storey extensions fall under permitted development, but it depends on your property and the size of the build. Your architect or the local planning authority confirms this at drawing stage, and we build strictly to the approved plans.
