Our story

A family firm, rooted on the Kent coast.

DCM Developments is a family-run construction company based on South Street in Whitstable. We're a professional, multi-trade building firm with over eight years experience across extensions, new builds, loft conversions and everything in between.

We take real pride in delivering an impeccable service. That means the right people on site on the right day, materials specified and ordered early, and a foreman you can actually reach on the phone. It's how a family firm should work.

Every home we build is a home we'd be happy to live in ourselves, and that standard is the one we hold ourselves to on every site, every day.

Client words

The work speaks.
So do our clients.

Averaging 4.9/5 across Checkatrade, Google and Trustpilot. The best reference, though, is always a walk-round with a past client. We'll arrange one.

★★★★★
DCM transformed our tired 1930s semi into a bright, open family home. The team were meticulous, tidy and finished a week ahead of schedule.

★★★★★
From planning through to the final snag list, communication was exceptional. You can tell they take real pride in their craftsmanship.

Loft Conversion · Whitstable
★★★★★
Used DCM for a full refurb and a new driveway. Fair quote, honest timeline and the finish is to a standard I didn't think was achievable.

Frequently asked

The things every
client asks us.

Still unsure about something? Pick up the phone. We'll give you a straight answer in five minutes, free of charge.

Many single-storey extensions and loft conversions fall under Permitted Development rights. We'll confirm at the consultation and handle any planning, building regs or party-wall applications on your behalf.

A single-storey rear extension is usually 10–14 weeks; a dormer loft 6–8 weeks; a full-house refurb 4–6 months. You'll get a fixed Gantt chart with every quote.

Yes. £5m public liability, TrustMark registered, CHAS accredited and working to the latest NHBC build standards. All electrical work is Part P certified and we issue Building Control sign-off on every project.

We use a staged-payment schedule tied to milestones you can inspect. No large up-front deposits. Everything is documented in a JCT Minor Works contract for peace of mind.

We're based on South Street in Whitstable and work across Kent: Canterbury, Herne Bay, Faversham, Margate, Ashford and surrounding villages.
