We’re innovators, designers and craftspeople with a passion for building beautiful furniture.

Jo White Design

When Jonathan Baulkwill and Chris Turner set up Opus Magnum in 1989, their focus was on high quality design, innovation and craftsmanship. They experimented with new materials, put the user at the centre of their designs and recognised the importance of a dedicated team.

Our finely tuned skillset and forward-thinking approach have meant we’ve worked on projects that include the Weston Library in Oxford, the Nicole Farhi flagship store in New York and the British Parliament.

We combine traditional craftsmanship with modern technology, from installing beautiful, cutting-edge fittings for corporate workspaces to sympathetically refurbishing listed buildings.

We take pride in our work, you’ll see that in the details, you’ll hear it in conversations with our team and you’ll know it when your furniture is still standing strong in years to come.

Opus Magnum is fortunate to have dedicated people that enjoy what they do for a living. This allows us to ensure high quality design, innovation and craftsmanship on every project.

In 2023 Opus Magnum transitioned to employee ownership to reflect this strong team commitment. 100% of the share capital passed from the founders to an Employee Ownership Trust where the beneficiaries are all the employees.

Our way

We live for extraordinary design.
It’s not just what we do, it’s who we are.


We see no limitations, only possibilities, especially when it comes to materials. We love working with different wood varieties, but what separates us from more conventional joinery firms is our deep understanding of other materials.

We’re always experimenting with new types of glass, steel, plastic and even aluminium honeycomb. This approach means we can present you with the best solution for your space and budget.

Then there’s the design itself.


Sometimes clients come to us with what they want, safe in the knowledge we have the experience and creativity to realise their vision. Others come to us with just an idea and it’s our job to explore the possibilities.

That’s what we love. That’s where our skills come into their own because we don’t just manufacture furniture, we problem solve and we’re great at finding answers no one else has thought about.

Made in London.

Different works well for us. It always has, so we keep doing it.


Unlike most commercial furniture companies, we craft all our furniture in our own workshop in South West London.

That’s our key to quality. We invest in the best equipment and the best people (a magical combination). We’re here to make the best commercial furniture, not the most.

Building good relationships is just as important as building good furniture. So, from design to installation, one team or individual will take full ownership of your project.
