One firm for the whole build — from the first drawing to the final finish.
A. Bunton Building Contractors is a building firm led by Adrian Bunton, working across Sevenoaks and the West Kent villages. We take on house extensions, loft conversions, whole-property renovations, kitchen refits, and patios & driveways — the larger building projects that turn a house into the home you actually want.
Because the building work is run by one firm and the trades are coordinated by us, you're not left chasing separate contractors or wondering who's responsible for what. Our Google reviews say the same things: the finish quality is high, the work is done on time, and people are simply happy with the result.
Our flagship work
House extensions and renovations, built by one firm.
An extension or renovation touches every part of a build — groundworks, steelwork, roofing, glazing and finishing — which is why splitting it across contractors so often goes wrong. We run the whole project as one coordinated job, so the programme holds and the standard stays the same from foundations to final coat.

How we work
From first consultation to final, surprise-free bill.
01
Site visit and honest advice
Adrian comes out, looks at the job properly and talks through what you're trying to achieve — what's possible, what's sensible, and where the money is best spent. There's no charge for the visit and no pressure to go ahead.
02
A clear written quote
You get a written quote setting out the work and the cost before anything is agreed, so you know exactly what you're signing up to — free, and with no obligation to proceed.
03
The build — coordinated and tidy
The building work is carried out by one coordinated team. We sequence the trades so the job runs in the right order, protect what we're working around, and keep the site clean as we go.
04
Finished on time, handed over properly
Reviewers tell us we complete the work in time and to a high finish. We don't call a job done until it's genuinely done — and we're glad to come back for the next project when you're ready.
Where we work
Based in Sevenoaks, building across West Kent.
We work throughout Sevenoaks and the surrounding West Kent villages — Riverhead, Otford, Kemsing, Seal, Chipstead, Dunton Green, Weald and Halstead among them. Being local means Adrian can get to site quickly for a look and stay close to a project while it's running. If you're nearby and planning building work, we'd be glad to come and take a look.
