sankyodo — Izumi Garden Tower 40F: light, a view, and deliberate empty space

A tax practice on the fortieth floor lists three things it designed for: natural light, the view over Tokyo, and the blank space needed to think in.

Concept

The third word on the list

Any office can claim light and a view from the fortieth floor. sankyodo puts a third word next to them: yohaku, margin — the empty part of the page. The company states that the floor was designed for light, view and margin, and defines the last as the space in which to turn a thought over.

You can see the decision in the plan. The desks are pushed out to the glass, so that looking up gives the city rather than a colleague’s monitor, and the middle of the floor is left comparatively open. The brand yellow appears exactly where it is useful — on the sign at the entrance, and on the columns that mark the long tables — and nowhere else.

01 · The entrance

Yellow, once

Stepping onto the floor, a sign in the brand yellow meets you against an otherwise restrained palette — a single accent, placed so that both visitors and staff get a clear first impression.

02 · The workspace

Desks against the glass

The working area is free address, with desks running along the window. The company describes the layout as close-knit enough that questions and small talk happen without arrangement.

Where the colour is allowed

The yellow returns on the columns that anchor the long tables, and nowhere else on the floor.

04 · Meeting

Glass rooms, and booths

Meeting spaces run from a small table to glazed rooms, and glass booths take web meetings with colleagues working remotely.

Forty floors up, at night

The same floor at night: the lights in the room drop, and the city becomes the wall.
