About Cube21

We are Cube21, a family-run commercial interiors firm based near Oxford, in Oxfordshire. We design, build, maintain, and furnish offices and laboratories, and we own the whole job from first design to final handover.

We are now in our second generation, with the next running the business day to day. That continuity matters. It means the people who answer your call have a long-term stake in getting your project right.

Everyone Pointing at Everyone Else

For years we watched fit-out projects go the same way. A designer here, a builder there, M&E from someone else, furniture from a fourth supplier, and a client left trying to hold it all together. When something slipped, everyone pointed at everyone else.



We built Cube21 to be the opposite of that. One team. One point of contact. One company accountable for the whole result.

Everything in-house. That is rare, and it is deliberate.

We self-deliver the heart of every project; design and 3D modelling, plumbing, heating, joinery, ceilings, flooring, and furniture and bring in trusted specialist partners for air conditioning and electrical. Whoever is on site, one project manager stays accountable throughout. That is rare, and it is deliberate. It is why we can commit to a programme and a price, and why we can stand behind the finished space.

What That Looks Like In Practice

Trusted by leading organisations across Oxfordshire and beyond.

Not the Cheapest Quote — the Safest Pair of Hands

Facilities and office managers, business owners, and lab and science-park leads who are making a big, deadline-driven decision and need to get it right.

Cube21 was incorporated in 2008 and is now run by its second generation. We are fully insured, self-deliver the core trades, and work with a settled circle of specialist partners for air conditioning and electrical. How we run a project, and the documentation we can provide before work starts, is set out on our How We Work page.
