银座东急广场位于日本著名的商业区--银座，同时也面临着主要的交通枢纽Sukiyabashi Crossing，是一座建筑面积达50,000平方米的大型商业建筑。该地点位于有乐町和日比谷区的连接点，可以说是 "银座之门"。该项目四面环路，是该区少有的 "1个街区全开发 "的项目。

Located in Ginza, which is the most renowned commercial district in Japan, and also facing a major junction Sukiyabashi Crossing, Tokyu Plaza Ginza is a large commercial building with a floor area of 50,000 sqm. The site sits at the connection point to Yurakucho and Hibiya disctrict, and can be described as “Gate of Ginza”. Surrounded by roads on all sides, the project is a “1 block full development” which is a rare case in this district.

建筑以“光之舟”的概念为基础，受到日本传统玻璃切割工艺“江户百合”的启发，设计成玻璃“舟”。为了实现一个与城市互动的商业建筑，外墙主要由玻璃组成。这将内部活动展现在城市面前，并使城市的感觉成为可能。

另一方面，三维立面的构成导致了来自阳光传输和反射的多样化的光学现象。立面显示出随时间和天气变化的各种表情。在以象征性的形式吸引人的同时，对周围城市景观和气候的反映使这个建筑与整个城市景观融为一体。东急银座广场是对银座城市景观的一个和谐的补充。

Based on the concept “Vessel of light”, the building is designed as a glass “vessel” inspired by the Japanese traditional craft of glass cut “Edo Kiriko”. In order to realize a commercial building which interacts with the city, the façade is mainly composed of glass. This reveals the inner activities to the city, and enables an urban feeling. On the other hand, the three-dimensional façade composition results in a diverse optical phenomenon derived from transmission and reflection of sunlight. The façade shows various expressions changing by time and weather. While attracting with a symbolic form, the reflection of surrounding cityscape and climate makes this architecture merge into the entire cityscape. The Tokyu Ginza Plaza is a harmonic addition to the urbanscape of Ginza.

作为城市现象的立面

这座东急广场银座大厦的立面由三维玻璃平面组成，营造出一种微妙的光反射和透射现象。换言之，立面以不同的方式反映了城市风光、室内商业氛围以及围绕这座建筑的动态活动。

通过重构这些不同的风景元素，建筑立面将自身转变为一种城市现象。采用 SSG 是为了不暴露玻璃的框架。就像在江户切子表面看到的雕刻玻璃图案一样，立面创造了一个巨大的 3D 菱形图案，高 6 层，深 500 毫米。

这种大规模的立面图案使建筑物从周围的环境中脱颖而出。单元化玻璃组件由低铁玻璃和热反射涂层玻璃组成，以一种强调建筑形式的三维轮廓的方式。低铁玻璃面板采用1mm梯度密度陶瓷圆点图案处理。晚上，这架飞机被集成在内部铝制竖框中的灯具照亮。

The facade of this Tokyu Plaza Ginza Building consists of three dimensional glass planes, which creates a delicate phenomenon of light reflection and transmission. In other words, the facade variously reflects the urban scenery, the interior commercial ambience, and the dynamic activities surrounding this building. By reconstituting these diverse scenic elements, the building facade transforms itself into an urban phenomenon. SSG was adopted so as not to expose the framing of the glass. Like a carved glass pattern seen on the surface of Edo Kiriko, the facade creates a large 3D diamond shaped pattern, which is 6 stories high and 500 mm deep. This large scale pattern of the façade makes the building stand out from the surrounding context. The unitized glass assembly is comprised of both low iron glass and heat reflective coated glass, in a way that emphasizes the three-dimensional profile of the building form. The low iron glass panel is treated with a 1mm ceramic dot pattern of gradient density. At night this plane is illuminated by light fixtures integrated into the interior aluminum mullions.

提升公共空间

KIRIKO LOUNGE是位于建筑中层的公共空间，提供了广阔的城市视野。通过其27米高的中庭，以及高于Sukiyabashi十字路口的有利位置，休息室向城市的商业活动开放。

The KIRIKO LOUNGE is a public space situated at the middle level of the building, providing a broad view of the city. By its 27 meter high atrium, and the vantage point above the heavy traffic of the Sukiyabashi Crossing, the lounge opens up to the commercial activities of the city.

在银座的高密度和有限的空间条件下，这样一个开放的高架空间为人们提供了聚集的机会，并创造了联系。建筑和城市背景之间的连续性促进了这个城市的吸引力。这种对城市空间的三维解读将产生一个新的机会，使人们的活动不仅限于场地内，而且还涉及到城市环境。

In the high density and limited spatial conditions of Ginza, such an open and elevated space offers an opportunity for people to gather, and create connection. The continuity between the architecture and urban context promotes the attractive nature of this city. This three dimensional interpretation of urban space will generate a new chance to produce activities not limited within the site but also involving the urban context.
