About us
We are specialist installers of SIPs (Structural Insulated Panels), based in Devon and serving the South West of England. JBR Buildings offers a complete design, manufacture, and installation service to ensure your SIP structure is delivered with precision and care.
With over 30 years of combined industry experience, we bring deep technical knowledge and craftsmanship to every project — delivering high-quality, energy-efficient buildings across England, Wales, and Scotland. Our skilled team of carpenters ensures each build is completed on time, on budget, and to the highest standard.
Located on the edge of Exmoor, we've been crafting timber-framed houses, conservatories, and outbuildings since 2006. From small residential projects to large-scale commercial developments, JBR Buildings is equipped to handle it all.
Planning & design
At JBR Buildings, we offer a complete, flexible design service tailored to suit your needs. Whether you’re collaborating with an architect, working alongside a main contractor, or managing a self-build project, our team will seamlessly integrate into your process to provide expert support at every stage.
We work closely with you to produce full working drawings, foundation plans, and a precisely scheduled delivery programme. This ensures not only that your SIP structure is engineered to the highest standard, but that it arrives on time and fits perfectly within your overall build schedule. From concept to completion, we’re committed to making your project run smoothly, efficiently, and with total confidence in the outcome.
The build process
At JBR Buildings, all SIP panels and glulam components are processed in-house at our dedicated workshop facilities in Devon. This allows our skilled team of carpenters and technicians to accurately cut, pre-assemble, and prepare every element to your exact specifications — with millimetre precision.
By carrying out this work in a controlled environment, we reduce the potential for delays, material waste, and on-site complications. Every component arrives clearly labelled, correctly sized, and ready for rapid installation, significantly cutting down build times and reducing labour costs.
The result? A faster, more predictable construction process that gives you greater control over your timeline and budget — all while maintaining exceptional quality and structural integrity from the ground up.
On-Site Assembly
Our dedicated on-site assembly team brings a wealth of practical experience and specialist knowledge to every build. With a background in SIP construction and a deep understanding of the systems we produce, our installers work with precision, care, and efficiency — ensuring each project is delivered on time, on budget, and to the highest possible standard.
For projects involving large-format panels or complex structural elements, we employ crane-assisted lifting techniques to guarantee safe handling and flawless placement. This approach not only improves site safety but allows for rapid, accurate assembly with minimal disruption to other trades.
Thanks to the pre-engineered accuracy of our SIP system, our builds come together cleanly and predictably — significantly reducing site waste, weather delays, and costly errors. The result is a high-performance structure that not only meets expectations, but consistently exceeds them in thermal performance, airtightness, and structural integrity.
Project management
Every self-build or extension project is different — and so is every client. That’s why at JBR Buildings, we offer a flexible project management service tailored to your needs. Whether you’re looking for full oversight from start to finish, or just need occasional input and coordination, we can step in as much or as little as required.
Our team can help manage:
Planning and design coordination
Foundation preparation and groundworks liaison
Material scheduling and delivery logistics
On-site coordination of trades and timelines
You stay in control, while we help reduce stress, avoid delays, and keep everything moving to plan. With JBR Buildings managing your SIP build, you’ll benefit from hands-on experience, clear communication, and a streamlined construction process — all backed by a team that understands your vision.
