— About the practice
Designing spaces that shape experience.
A London commercial interior design practice with more than thirty years of international experience delivering award-winning workplace, hospitality and commercial environments.

— A note from the founder
“We do not design rooms. We design the quiet architecture of how a business is felt — by its people, its clients, and the city around it.”
James Ellingworth · Founding Partner
— 001 · Our philosophy
Restraint, over noise.
We believe the best commercial interiors are the ones you notice second. First, you feel the room work — the light, the acoustics, the way a team gathers or a client is received. Then, slowly, you begin to read the detail.
Our work is rooted in a British tradition of quiet material craft — hand-finished timber, honest stone, considered brass — and a modernist discipline of proportion and plan. We design for longevity, not the trade press.
We keep every project under the direct care of a founding partner. Nothing leaves the studio without our name on it, and nothing goes on site without one of us there.
— 002 · Our approach
A method, four movements.
- 01
Listen
We begin with the business — how it works, what it values, where it is going. Design follows understanding, not the other way round.
- 02
Interpret
We translate strategy into space: floorplates, adjacencies, materials, light. Every decision is tested against the brief.
- 03
Refine
We prototype at scale — mock-ups, samples, walk-throughs. Nothing is left to the site.
- 04
Deliver
We lead the site from first strip-out to final commissioning. The team that designed it is the team that hands it over.

— 003 · International experience
