PharmaEssentia Japan — Tokyo: taking down the wall next door

PharmaEssentia Japan, the Japanese arm of Taipei-based PharmaEssentia, develops treatments mainly for blood diseases. It moved in with about 20 staff in April 2021; when the neighbouring unit came free, with staff already tripled, it expanded to about 934 m² for 63 people with UCHIDA YOKO.

Concept

Walls down

At first the owners would allow only a door between the two units. After checks on the structure and fire rules, almost all of the dividing wall was removed.

With the wall gone, the west windows and their view are open to everyone, and guest and staff-only zones could be separated at the entrance.
