Side return extension on a 1905 Victorian terrace. Demolished the side return + rear walls, dropped in a goalpost steel across the new opening, built out into a 4.5m wide kitchen-diner. Full-length pitched-glass rooflights. Kept and exposed the original brick chimney breast as a feature wall. Bespoke oak-veneered units, quartz worktops, engineered oak flooring throughout. Family stayed in the house the full 18-week build — temporary kitchen in the utility, dust managed with zip walls. Snagging visit two weeks post-handover; zero items to revisit.
About
DC Builders
DC Builders is a Belfast-based building contractor founded in 2019. We're a 16-strong team running two to three crews at any given time, working on extensions, full home renovations, kitchens, bathrooms and small-to-mid new-build domestic projects across Greater Belfast. We've grown deliberately — every site has a named project lead who's on it from first ground-break to final snag.
What do you specialise in?
Rear and wraparound extensions, full property renovations where we co-ordinate joinery, plastering, plumbing and electrics under one project plan, small new-builds, and the occasional commercial fit-out for cafés or small offices. Two of our crews run residential, one runs light commercial — you'll know which one is on your job before we start.
What sets you apart from other tradespeople?
Three things. Every job is fixed-price in writing within five working days of the site visit — no surprises mid-build. Every job runs under one named project lead so you've always got one phone number, not five. And almost nothing is sub-contracted — we have full-time in-house joiners, plasterers and groundworkers, plus our own plant.
What kind of jobs do you love taking on?
Mid-budget full renovations where we can manage the whole job under one roof — rip-out to handover. Wraparound extensions on family homes that need real structural work done properly with engineer drawings. Smaller commercial fit-outs where a business owner wants one number to call and a fixed date to open the doors.
How do you ensure quality on every job?
Every project ships with a written programme and weekly milestones — you can see exactly where we are on the build any given Friday. The crew foreman signs off the previous trade's work before the next one comes in, no hand-off slippage. Every job ends with a two-week post-handover snagging visit included in the quote. We're CHAS-accredited and Constructionline Gold for the commercial side.
What should homeowners know before contacting you?
Typically booked 8-12 weeks out for new starts — get in touch as early as you can if you've got a target completion date. We cover Belfast, Lisburn & Castlereagh, Ards & North Down, and Antrim & Newtownabbey. We're set up for projects from around £25k upwards — below that you'd usually be better served by a single-crew local builder, and we're happy to point you towards one. Free site visits and fixed-price quotes either way.
