客户是一家开发公司。它购买了银座一块令人向往的地段，计划建造一座商业/办公楼。建筑用地位于银座1丁目煤气灯街，就在银座中央大街的后面一条街。它位于中央大街上瑞穗银行和宝丽银座大楼的后面。这里的氛围与繁华的中央大街截然不同，这个地段常常是在大型建筑的街道后面才能看到的空旷街道。吸引尽可能多的人进入这样的街道是我们的任务。客户希望这座建筑成为一个华丽的存在。此外，设计师希望为路人提供一种“轻微的陌生感”，以吸引他们注意这座建筑。
考虑到从内部获得的视野，简单地通过玻璃获得开放性似乎是徒劳的，因为外部的风景令人绝望。因此，采用了双层结构，包括玻璃幕墙和经过图形处理的铝制冲孔金属。立面成为室内装饰的一部分，省去了百叶窗或窗帘等窗户处理的需要。通过使用双层结构，还旨在减轻空调负荷和玻璃清洁负担。
不规则的立面设计是通过计算设计来避免任意形式并逼近自然形式的结果。我们认为，一个精心制作的附带形式可能会是一种较为宜人的设计。在主要是水平和垂直或几何形状的现代主义建筑的周围，这座建筑具有适当的陌生感，引起特别关注，并具有作为商业建筑的吸引力。抽象的花朵图形用于平衡立面的印象，即使它不会变得过于尖锐。
通过计算设计，个别铝制冲孔板是不规则的，具有不同的角度和形状，但都适应标准尺寸，因此材料利用率非常高。为了避免显得笨重，需要极轻的结构。因此，在其细节上要非常小心。安装在双层结构内部的彩色LED顶部照明根据季节的不同节目让过路人感到愉悦。预计的租户包括美容沙龙和美容沙龙，期望正在实现。
The client is a developer company. It purchased a long-sought after lot in Ginza, and planned to build a commercial /office building. The building site is on the Ginza 1-chome Gaslight Street, which is one street behind the Ginza Central Street. It is on the back side of the Mizuho Bank and Pola Ginza buildings on the Central Street. The atmosphere is quite different from the gorgeous Central Street, and the site is on an empty street which is often seen behind the street with large-sized buildings. Attracting as many people as possible into such a street is our task. The client desired the building to be a gorgeous existence. In addition, the designer desired to provide a “slight feeling of strangeness” to the passersby that would attract them to the building.
Considering the views from the inside, simply obtaining openness with glass seems futile, since the outside scenery is hopeless. Therefore, a double skin structure is employed, which consists of glass curtain walls and graphically treated aluminum punched metal. The façade becomes a part of the interior decoration and obviates the need for window treatments such as blinds or curtains. By using a double skin, reduction of the air conditioning load and the glass cleaning burden was also intended.
The irregular façade design was determined by computing a design to avoid arbitrary forms and to approximate forms in nature. We thought that a well-made incidental form would likely be a less-disagreeable design. In the neighborhood of mostly modernist architecture with horizontal and vertical or geometric shapes, the building has a proper feeling of strangeness, attracts special attention, and has an appeal as a commercial building. The abstract flower graphic is used to balance the impression of the façade, i.e., to free it up from becoming too edgy.
By computing the design, individual aluminum punched panels are irregular with different angles and shapes, yet all fit into a standard size, resulting in excellent material yield. To avoid being clunky, an extremely lightweight structure is required. Therefore, much caution was taken in its details. The colored LED upper lighting, which is installed inside the double skin, entertains the passersby with different programs depending on the season. Expected tenants included a beauty salon and esthetic salon, and the expectations are materializing.
