日本最大の問屋街、東日本橋に立つ卸売店舗ビルの改修プロジェクト。5万点という大量のストックを店内に納めつつ、ディスプレイとしても商品に目が向く内装が求められた。圧倒的な物量・短工期・低予算のなかで、独自の個性を持つバイヤーの世界観を邪魔せず引き立てる店舗が求められた。問屋街は視界に必ず段ボール箱が入るほど、段ボールとともに成立する商業形態である。そこで、地券紙(古紙を原料とした無着色の原紙)を用いたグレーの段ボール板を用いて、5万点全てを収納できる2サイズの引出し箱を設計した。無着色の段ボールは茶色より抽象度が高く、バイヤーの世界観を阻害しない。また商品ディスプレイ部は、無垢の国産桧角材で単純なフレームを現場で製作した。現場では工場で組立てられたおよそ3000個の引出し箱と、桧フレームを積み上げるのみとし、150坪の店舗内装(1~3階)を2日間で組み上げた。箱を積み上げる操作のみでプロポーションも環境も異なる複数の空間に分割しつつ、全体がゆるやかにつながる環境体をつくりあげた。

段ボールはシングルの場合、両面の紙2面+芯をなすフルートの3層構造となっている。グレーの地券紙は強度的には茶色紙には劣る。そこでその3層構造を生かし、両面2面を地券紙、表面に見えてこないフルート部分に強度の高い茶色紙を使い、まずは段ボール板自体の強度確保を目指した。最終的に、意匠性・強度・組立て時の折曲げ精度などあらゆる観点から、紙の厚みを示す米坪にて「190(g/㎡)・S160(g/㎡)・190(g/㎡)(=地券紙・茶色紙・地券紙)」の組み合わせを選択した。さらに、3層に貼り合わされた段ボール板は、特注の木型によって工場にて切り分けられる。組立て時に引出し開口部を補強し、段ボール箱の積石造に耐えうる強度を実現した。

A renovation project for a wholesale store building located in Higashi-Nihombashi, Japan’s largest wholesale district. The design of the store involves both the display areas and the storage ones, which have to stock up to 50,000 pieces of clothing. Other than deal with this overwhelming physical quantity, the process involved short construction term and low budget.

The goal of the design was to create a store that complements the surrounding still keeping its own individuality.
The wholesale area is a commercial form familiar with the use of cardboard box, constantly present in the area. Therefore, we based the renovation design on the use of the box: made of special grey corrugated board (un-pigmented base paper made from waste paper), the boxes come in two different sizes and can store all the 50,000 items.
The gray corrugated cardboard has a higher degree of abstraction than brown and does not hinder buyers’ view. In addition, in the product display section, we produced a simple frame with solid Japanese domestic pine wood. The 3000 drawer boxes were factory assembled and stacked up on site, together with the pine frame. We built up approximately 500 m2 of store interior (1st – 3rd floor) in 2 days.
While dividing the environment into multiple spaces with different proportions only by the operation of piling up the boxes, we created a space that gently connects the whole body.

In the case of a single cardboard, it is usually formed by a three-layer structure of two sides of paper and one forming the core. The grey paper used in this projects is inferior to the standard brown cardboard in terms of strength. So, by making use of the three-layer structure, we aimed at securing the strength of the corrugated board first, by using two sheets of special grey paper and a central part which is not visible on the surface, made with high-intensity brown paper. 190 (g / m2) · S160 (g / m2) · 190 (g / m2) (= Bond paper, brown paper, bond paper) paper were used. In this way the paper answers to all the design requirements, from all perspectives, including design flexibility, strength and folding precision at the time of assembly.Furthermore, the cardboard can be easily carved at the factory with a custom pattern.
During the assembly, the drawer opening was reinforced to realize a strength similar to masonry.
