A Norfolk builder you canactually get on the phone.Owner-managed groundworks and general building since 2000.
Jason Humphries has spent 25+ years on the tools across King's Lynn and West Norfolk, from footings and drainage to full rear extensions and driveways. Every job is quoted, run and finished by the same person, so nothing gets lost between salesman, project manager and site.
Who we help,
and what we're built for.
Humphries Construction was founded by Jason Humphries in East Winch, Norfolk, on a simple idea: homeowners and small developers deserve a builder who quotes honestly, turns up when he says he will, and finishes the job to the same standard on day one as on day forty.
Who we help. Norfolk homeowners planning single or two-storey extensions, families converting a garage into usable living space, landlords upgrading rental properties, and small developers needing reliable groundworks and foundations on new-build plots up to eight units.
What we specialise in. Groundworks, foundations and footings, drainage, extensions, garage conversions, brickwork, driveways, patios and landscaping. We stay inside the disciplines we know cold rather than pretending to do everything.
Experience depth. Over two and a half decades of Norfolk ground, Fen peat and silt around King's Lynn and Wisbech, Breckland sand around Swaffham, chalk around Hunstanton, and coastal clay near the wash. That local knowledge saves customers money on ground-condition surprises other builders discover mid-dig.
Where we work. King's Lynn, Norwich, West Norfolk, Downham Market, Swaffham, Fakenham, Hunstanton, Wisbech and Dereham. If your postcode is inside a 40-minute drive of East Winch, we'll come out for a free survey within 7 days.

from first call to handover.
Fixed written price

One point of contact
Jason personally runs every project. No call centre, no rotating site managers. Same number, same voice, from quote to snag-list.

£1,000,000 public liability cover, 10-year structural warranty on extensions, and a 2-year workmanship guarantee on garage conversions.
Correct spec, first time
We build to Building Regulations Part A, Part C and Part L as a baseline, not as an argument. Steel, footings and drainage go in to engineer's spec, always.
Realistic timelines
You get a written programme with survey, design, planning, build and snagging phases. If weather or supply delays hit, you hear about it the same day.
Trusted long-term trades
Jason brings in the same core team of subcontractors he's worked with for years, groundworkers, bricklayers, roofers. All fully trained and carrying their own insurance. No day-rate strangers walking off site when a cheaper job comes up.
