Two decades of building Yorkshire homesthat last a generation.
Founded in 2004 by Danny Johnson, we are a family-run building firm trusted by 800+ homeowners across Barnsley, Sheffield, Wakefield and the wider Yorkshire region — delivering extensions, loft conversions and full renovations finished to a standard you'd be proud to put your name on.
A trade business built on word-of-mouth, not flashy marketing.
Danny Johnson started laying bricks at sixteen. Twenty years later, Johnsons Building Services employs a settled team of bricklayers, joiners, plasterers, electricians and Gas-Safe plumbers — all directly managed, all paid properly, all answerable to one project lead per job.
We don't subcontract jobs out and disappear. The same site manager who quotes your extension is the same person who hands you the keys to your finished kitchen-diner. That continuity is why 71% of our work in 2024 came from referrals or repeat clients.
Our specialism is structural domestic work — single and double-storey extensions, loft and garage conversions, kitchen and bathroom installations, and whole-house renovations. We don't chase commercial fit-outs or new-builds. Yorkshire homes, done properly, is all we do.
The standards every job is held to.
Built to Building Regs +
Every structural element exceeds current Building Regulations. We submit drawings, arrange inspections, and hand you the completion certificate.
Fixed written quotes
No day-rate guesswork. You receive a line-itemised quote within 48 hours that locks in labour, materials and timeline before we start.
10-year workmanship guarantee
If anything we built moves, leaks or fails because of our workmanship within 10 years, we return and fix it at our cost. In writing.
Service philosophy — six non-negotiables
Numbers that matter when you're trusting someone with your home.
