这个商业综合体为一家历史悠久的音乐公司服务，包括音乐教室、乐器销售和存储空间，以及公司的主要办公室。该项目位于东京的神田-御茶水地区，该地区以其众多的音乐商店而闻名，地块很小，形状不规则。客户要求建筑能有效地结合各种功能，包括钢琴、小提琴和其他乐器的课程室；演奏会的大厅；专业录音设备店；乐器批发销售的仓库；以及管理这些业务的各个方面的办公室。

This commercial complex for a music company with a long history includes music classrooms, instrument sales, and storage spaces, and the company’s main offices. Located in the Kanda-Ochanomizu area of Tokyo, which is known for its many music stores, the lot is small and irregularly shaped. The client requested a building that efficiently combined a variety of functions, including rooms for lessons in piano, violin, and other instruments; a hall for recitals; a professional recording equipment shop; storage for wholesale instrument sales; and offices to manage these various aspects of the businesses.

每层楼的隔音、视野、采光、遮阳和使用时间等相关要求都不一样，而且这些要求在未来发生变化的可能性也很大。因此，我们决定使用双层膜，无论房间如何使用或窗户是否打开，都能保持统一的外部外观。我们选择了一种在高海拔地区摇摆的网状膜，可以很容易地在各个方向上圆滑，以实现最佳的天空视野比例，并且对光线和空气是多孔的。

The requirements related to soundproofing, views, daylighting, shade, and usage time varied for each floor, and the likelihood that these requirements would change in the future was high. We, therefore, decided to use a double skin that maintains a unified exterior appearance regardless of how rooms are being used or whether windows are open. We selected a mesh membrane that sways at high altitudes, can easily be rounded in all directions to allow for optimal sky-view ratios, and is porous to light and air.

由涂有PVC树脂的聚酯纤维制成的防火外网膜，既能阻挡外面的视线，又能让里面的人看到外面。33%的太阳反射率使空调负荷降低了28%。该膜可以三维弯曲，由于它很轻，而且是穿孔的，无论是材料本身的重量还是风压，都没有什么结构压力。因为没有与材料落地有关的危险，所以它很容易更换和维护，可以重复使用。covid-19的大流行增加了像这样的外墙的吸引力，在保持隐私的同时加强自然通风。

Made of polyester fibers coated with PVC resin, the fireproof exterior mesh membrane blocks visibility from the outside while allowing those inside to see out. A solar reflectance rate of 33 percent lowers the air conditioning load by 28 percent. The membrane can be bent three-dimensionally, and because it is light and perforated, there is little structural stress from either the weight of the material itself or wind pressure. Because there is no danger related to the material falling to the ground, it is easy to replace and maintain and can be reused. The covid-19 pandemic has increased the appeal of facades such as this that enhance natural ventilation while maintaining privacy.

建筑的形式考虑了不规则的地段形状，与高度和后退有关的法规，以及必要的元素，如紧急楼梯、阳台、管道和线路，以及表达公司身份的需要。我们纳入了从各种乐器中获得的灵感的形状，并对其进行了调整，以使容量最大化。网状覆盖的立面让人联想到一个向附近发送音乐的扬声器，将建筑转化为一个巨大的标志，宣传里面的公司。

The form of the building considers the irregular lot shape, codes related to height and setback, and necessary elements such as emergency stairs, balconies, plumbing, and wiring as well as the need to express the company’s identity. We incorporated shapes inspired by various musical instruments, adjusted to maximize capacity. The mesh-covered façade evokes a speaker sending music into the neighborhood, transforming the building into a giant sign advertising the company inside.
