CARTA HOLDINGS — Toranomon: a plaza, an oasis, a garden and a hideout, on three floors

Thirty-six to thirty-eight in Toranomon Hills Station Tower, arranged under the phrase 4 EVOLUTiON and divided into named rooms — a plaza, a library called OASIS, a bar called AJITO, a café called GARDEN.

Concept

Four names that are not English and not quite Japanese

The floors are laid out as a set of named rooms, and the names are the point. PLAZA is the multi-purpose area. OASIS is the library. GARDEN is the café. And AJITO is the bar — ajito, a word Japanese took from the Russian agitpunkt and turned into the word children use for a den.

A holding company assembled out of several advertising and media businesses has a particular problem: the people in it did not choose each other. Giving the shared rooms names that anybody can say, rather than numbers off a plan, is the cheapest available way of making a single address out of several companies. The entrance sets the tone — a long curved white wall that bends you round the corner before the floor opens up.

01 · The entrance

A curve, then the floor

The entrance is a long white wall curved in plan, so that the working floor is not visible until you are round it.

02 · PLAZA

The room that is not for anything in particular

PLAZA sits under a ring of light and takes tables, plants and loose seating — the multi-purpose room, kept deliberately unassigned.

03 · OASIS and LAB

Books, and rooms for visitors

OASIS is the library: shelves on two levels with reading seats built against them. LAB is the set of meeting rooms kept for people from outside.

04 · AJITO and GARDEN

A bar, and a café

AJITO is the bar — dark red chairs, a low ceiling, the city behind the glass. GARDEN is the café, with a serving counter and planting along the edge of the floor.

05 · STUDIO and the working floors

Where the broadcasting happens

STUDIO is fitted for livestreaming. The main floor is open desking, with the atrium cutting through it and open meeting rooms set along the glass.
