Local builder · Saffron Walden & Cambridge
One firm managing the whole build — from the footings to the final sign-off.
JRB Builds is a building firm run by James Bruno — known to most customers as James or Jamie — based in Saffron Walden. We take on new builds, single and double-storey extensions, garage conversions, patios, driveways, brickwork and the wider building work homes across the Uttlesford district need.
Because we manage the whole project and coordinate our trusted trades — Al Platten Electrics for the wiring, Warmtouch for plumbing and heating — you deal with one team from start to finish. Our reviews say the same things again and again: communication is excellent, the work is high-standard, and the site is kept clean and tidy throughout.
Our signature work
Extensions & new builds, managed from footings to sign-off.
Single and double-storey extensions, ground-floor WC additions and full new builds — with the structural work handled, aluminium windows and rendered fronts fitted, and every trade coordinated. As one review puts it: “handled all structural work, and managed every trade professionally… completed on time, on budget, and fully signed off by building control.”

In their words
“James and the team at JRB BUILDS were fantastic from start to finish. They transformed three downstairs rooms into a stunning kitchen-diner, handled all structural work, and managed every trade professionally. Our front extension, new downstairs toilet, and multiple additional features were all completed on time, on budget, and fully signed off by building control.”

“JRB converted part of our garage to an office/studio and I can't recommend James and the team more highly. James was incredibly communicative throughout and we are very pleased with the standard of work. They were very accommodating with changes throughout the project, kept the site clean and tidy, and completed everything within the time they suggested.”

“We used JRB Builds to lay a patio and make improvements to our garden, including creating a low brick wall and a couple of planters. Communication was great, the work was carried out efficiently and to a very high standard, and they came up with some good ideas for dealing with a couple of tricky areas. On top of that, they were a really nice bunch of people!”

“Even though we made a few changes along the way, the project still came in on budget which we really appreciated. Whenever anything unexpected came up, the team were always able to find practical and creative solutions rather than letting things turn into a problem. JRB worked well with other trades — they coordinated seamlessly with our usual plumber Warmtouch and introduced the electrician team, Al Platten Electrics.”

“What really elevated James and his team above the rest was their help, support and guidance in the work we had chosen to take on ourselves. Rob and Paul would take the time to explain the best way of doing whatever job we had taken on. By the time their job was done, it felt like we were saying goodbye to friends. Top Work, Top Team, Very happy — 100% recommend.”

How we work
From first consultation to a signed-off handover.
01
Consultation & honest advice
James comes out, listens to what you want to achieve and gives genuinely useful, practical advice on what the project needs — including help and guidance on any parts you plan to take on yourselves. No pressure, no charge for the conversation.
02
Design, structural & building control
We coordinate with your architect and structural engineer where needed, and liaise with Uttlesford building control ourselves — so the design that’s agreed can actually be built, and the paperwork is handled for you.
03
The build — clean, tidy, coordinated
James and the team — including Rob and Paul — carry the work through, bringing in Al Platten Electrics and Warmtouch to keep first and second fixes on schedule. The site is kept clean, and neighbours are considered with parking and deliveries.
04
Sign-off & handover
Structural work is signed off by building control, waste is removed, and the project is finished to a high standard — “on time, on budget, and fully signed off,” as our reviews put it. Many customers book us straight back for the next stage.
Where we work
Based in Saffron Walden, at home across Cambridge & Uttlesford.
We work throughout Saffron Walden and the wider Uttlesford district — Newport, Thaxted, Great Chesterford, Stansted Mountfitchet, Great Dunmow and the surrounding villages — and out into Cambridge and its southern villages such as Linton and Sawston.
