The Design

About Nippo Junction Siège Social

Le siège social de Nippo est construit au-dessus d'une intersection à plusieurs niveaux d'infrastructures urbaines, d'une autoroute et d'un parc. Nippo est une entreprise leader dans la construction de routes. Ils définissent Michi, qui signifie «rue» en japonais, comme la base de leur concept de design comme «ce qui relie une variété de composants». Michi relie le bâtiment au contexte urbain et connecte également les espaces de travail individuels les uns avec les autres. Michi a été amélioré pour forger des liens créatifs et pour faire du Junction Place un lieu de travail unique possible uniquement ici chez Nippo.

Unique Properties: This project is rebuilding the Nippo Head Office built over a multilayered intersection of urban infrastructure, an expressway and a park. Nippo is a leading company in road construction.
By drawing this multilayered intersection of Michi (street in Japanese) on laminated workplace, Michi connects not only physical spaces, but also the individuality and distinctiveness of each place.
Michi was enhanced to forge creative connections and to realize a unique work place possible only here at Nippo.
Dimensions & Packaging: Composition of Double-skin Façade on north-west side
1. Fan shaped outer skin
- Two-sided support system with frame and SSG System
2. Fan Stone provides support to counter wind forces on both skin layers
- A dynamic facade composed from stone mullions and glass panels expresses both the forward looking and reliable company identities
3. Completely flat mullion-less MPG inner skin
- enables use of inner spaces directly up to glass panels

Production Technology: The Edge between urban environment ,Facade
Double skin glazing on the north-east sides are arranged in a staggered folding fan layout optimized for natural ventilation, reduction of direct sunlight and opening out to vistas, actively engaging prevailing winds and direct sunlight, and minimizing usage of blinds. The cavity between double skin glazing is used for natural ventilation and for reducing wind speed and ambient city noises to provide an open workplace connected to urban elements
Design Challenge: The Metropolitan Expressway runs at the foot of the new headquarters. The Metropolitan Expressway is a river before the Tokyo Olympics. Therefore, a revetment retaining wall of the river was left in the site, and it was necessary to construct the basement while leaving it. A seismic isolation structure is adopted so that the headquarters function can be maintained even in the case of a large earthquake.
Research: Japan needs an exterior plan to prepare for typhoons, and very careful consideration was required for setting the wind pressure of the double skin facade. Since this exterior incorporates a stone, by setting the interlayer displacement and construction accuracy at the time of the earthquake carefully, a very delicate exterior is realized.
Inspiration: The Michi is also expressed in the NIPPO logo and slogan, which is also the identity of this company. We regard Michi as the connection between various elements, and put Junction into the concept. Specifically, it is an attempt to reorganize the connection between neighboring cities and the connection between work places, which were sparse at the former head office, with the new head office plan. At the same time, it is a plan to re-identify the identity of a company.
Project Duration: Completion: 2018/6
Location: Chuo-ku, Tokyo,JAPAN
Operation Flow: Columns are placed between Quiet Michi and Ie spaces, defining a soft boundary. Each department or team can set its own relationship with Michi by variating the layout of the Ie zones for column intervals. The columns have inserts that allow a wide variety of boundaries to be set up according to worker needs. such as soft boundaries defined by furniture or partitions between columns and privatizing the Michi for how each space is used is possible
