Not “weekend off-grid” — genuinely self-sufficient vans designed for extended travel, wild places, and all seasons, without relying on campsites.
Every layout, system and material choice is driven by how the van is actually used — bikes, wet kit, cold weather, long days outside.
We offer a carefully structured level of customisation, working closely with you to understand how you travel and guiding decisions to ensure the finished van works beautifully — and remains true to the Onyx ethos.
Our background includes complex, off-grid builds beyond traditional campervans — including expedition and overland vehicles — informing the robustness, systems thinking, and problem-solving in every Onyx van.
After handover, you deal directly with the team who designed and built your van — for advice, troubleshooting, or future changes - so we can make sure you get the most out of your new build.
“I’ve had an absolutely great experience with Onyx Vans, delivering a very professional and high standard work. I value their honesty and quality of work very much. They are friendly, helpful and give you the best advice for your needs so that you get the best outcome. They pay special attention to detail and resolve to finish the work quickly, which is great and they go above and beyond expectations. I have a great deal of respect for this team and recommend them 100%.” — Nita G
“Onyx created the van of my dreams. I work in interiors and had a clear vision of what I wanted. Flexibility in the layout and uncompromising quality were key. I searched the South East for the right partner to bring it to life, visiting three van builders in total. Onyx was the last, and wow, what a difference. The workshop was professional, spotless, and equipped with the latest machinery. I could tell straight away that they cared about the details. Great coffee and a lot of Yeti cups. Always a good sign! Chris and Heather were fantastic to work with. We visited the workshop multiple times during the build to work through the finer details. Communication was excellent, costs were transparent, and they weren’t afraid to push back on a few of my ideas. The van is better for it. The finishing detail is second to none. Since picking it up in April, we’ve used it almost every weekend, and we absolutely love it. The aftercare has been brilliant too.” — Debbie W.
