Dai-ichi Life — Toyosu: a floor with no partitions at all

One of Japan’s oldest life insurers runs its Toyosu office on a single rule: no partitions. The desks sit left and right of a central free space, and between them are focus boxes, phone booths and booth seats borrowed from a family restaurant.

Concept

Take the partitions out and see what happens

The floor desks sit on either side of a central free space, and they are described in one phrase: a single-floor design with not one partition, so that people can talk to each other easily and comfortably.

Everything else follows from that. Because the desks are open and unassigned, the floor needs somewhere to concentrate and somewhere to take a call — so the quiet places are built as objects placed on the floor rather than rooms cut out of it.

01 · Central free space

Meetings at noon, lunch at one

Walk in and the central free space is the first thing you reach. It is used for internal meetings, and at lunchtime it becomes where people eat.

02 · Floor desks

Left and right of the middle

The desks run either side of that space. Free address is the norm, and meeting spots and work surfaces are scattered right through the floor rather than gathered at one end.

03 · The agile workshop

Focus boxes around a hexagon

The area the company calls the agile workshop is a set of focus boxes around a six-sided meeting space in the middle. Inside a box you can work without noticing anyone around you.

Beside the desks are booth seats built in wood with planting around them, used when someone wants to change the feel of the day, and also for meetings and for lunch.

The rooms with doors

Proper meeting rooms, a relaxation space, and a shared area at the void that runs through every floor finish the tour.
