About Hartwell & Stone

Building Britain's Finest Homes Since 1987

James Hartwell founded this company in 1987 with a simple conviction: that every project — regardless of scale — deserves the same uncompromising standard of craftsmanship. He started with two employees, a Bedford van and a reputation built on doing things properly.

Nearly four decades later, Hartwell & Stone has grown into one of the South East's most respected construction companies, with over 45 directly employed staff and a portfolio spanning bespoke new builds, heritage restorations, elegant extensions and barn conversions. We've won industry awards, earned the trust of architects across the region, and completed 487 projects — but we've never lost the personal approach that built our reputation.

What sets us apart is simple: we directly employ our tradespeople. Our carpenters, bricklayers, plasterers and heritage specialists are part of the Hartwell & Stone team — not subcontractors who move between sites. This means consistent quality, clear accountability and a genuine pride in the work that clients notice immediately.

Every project is led by a dedicated project manager. Every client has direct access to our senior team. Every build is backed by our 10-year structural guarantee. Over 60% of our work comes from referrals and returning clients — and that, more than any award, is the measure we're most proud of.
