Towering ceiling voids, a dedicated cinema room and thoughtfully designed focus areas come together in a space built for deep work. The lower ground has been transformed into a smart, efficient environment originally fitted out for visual-effects production — fibre-connected screening and review rooms, a dedicated machine room, and meeting rooms finished in natural materials. Calm, focused and quietly creative, with soft lighting and clean lines throughout.
Towering ceiling voids, a dedicated cinema room and thoughtfully designed focus areas come together in a space that truly works. The lower ground has been transformed into a highly attractive environment, using a smart, efficient configuration that feels anything but secondary.
The original brief called for intelligent use of naturally darker areas to support deep, focused work, alongside fibre-connected screening and review rooms and a dedicated machine room. The cinema room is fully adaptable — natural light or complete blackout, with highly absorbent acoustic materials — making it as suited to team huddles as to screenings.
