Mitsui & Co. Plastics — Otemachi: red stools at the end of the floor

A plastics trading company on a landmark Otemachi floor keeps the visitor route and the staff route apart, and finishes the staff end with a timber counter, a tiled wall and a row of red stools.

Concept

Five spaces, named plainly

The company sets its office out in five pieces and gives each of them a one-line description: the building, a landmark in Otemachi; the entrance, the front door of the company; the guest space, where clients are received; the work space, the base of the working day; and the communication space, where you can refresh.

What makes it work is that the five are laid out as two routes. A visitor arrives, is received and shown to a room. Staff pass through to the desks, the phone booths, the planted meeting area and the counter at the end.

The front door of the company

The lift lobby is shared; the company’s own entrance is a quiet wall, a sign and a single arrangement of flowers.

Timber screens, then red

A screen of timber posts and planting separates the last stretch, and the floor ends at a counter with a tiled front and red stools along it.
