Henry James Building is an independent building company based at 52 Duke Street, Darlington. We put our name on every local job we take on and do it the way it ought to be done.
You deal with our team directly, from the first site visit through to the final walkthrough. Our settled, in-house crew take real pride in their work and turn up when they say they will. Extensions, loft conversions, heritage work, roofing, groundworks and structural alterations. Every trade covered in-house, and everything we hand over is backed by the team that built it.
When you call, you get the team direct, not a call centre. We come out to your property, talk the job through properly, and the same faces are on site from the first day to the last. We don't disappear once the invoice is paid. The Henry James team
Every job follows the same four steps. Someone from the team on every visit, the same in-house trades across every project, regular updates, and a full handover at the end.
We visit the property, review the scope, and give you honest advice on viability, programme and budget.
We coordinate drawings, structural calculations, planning and building control, and issue a fully itemised quote.
Our in-house team runs the job end to end. Clean working, weekly updates, handed over on the agreed programme.
Final walkthrough, snagging, signoff and warranty documents. Aftercare continues long after the final invoice.

Happy to put you in touch with recent clients across Darlington, Durham, Stockton and the wider North East.
A handful of recent clients across Darlington, Durham, Stockton and Middlesbrough. Every one a real build, every one completed by the same settled local team.
Genuinely the smoothest building work we've ever had done. They finished on time, held the price they quoted, and the kitchen is better than we'd pictured. We wouldn't think twice about having them back.
Really happy with our loft conversion. The standard of the woodwork alone was worth it, and when they finished there was honestly nothing left for us to chase up or put right. That's a first for us, after three other builders over the years.
Our driveway and front garden look brilliant. They gave us a fair price, actually finished a week early, and the standard of the work is lovely. Five of our neighbours have already asked who did it.
Our house is Grade II listed, so we were really nervous about who to let near it. They clearly knew how to work on an old building, used the proper lime mortar and brought the original sash windows back to life. Even the conservation officer was pleased with how it turned out.
We needed our new office fitted out in a tight ten week window and they hit it spot on. They kept us in the loop every week and the electrics and plumbing all came together without any fuss. Fair pricing, clearly broken down. Would happily recommend them.
They did the groundworks and foundations for our new build. It's an awkward site with tight access and a few drainage headaches, but they sorted every problem before we'd even spotted it. It passed inspection first time with nothing to go back and fix.
Our home base is 52 Duke Street, Darlington DL3 7AJ. We take jobs across County Durham, Tees Valley and the wider North East, typically within an hour of the office. Outside the area? Ask anyway, we still might cover it.
