Appreciation towards Aisaka Architects’ Atelier for providing the following description:

项目是Aisaka Architects’ Atelier团队为一家位于东京神田御茶水地区的历史悠久的音乐公司打造的商业综合体。该地区以拥有众多的音乐商店而闻名，本次需求设计的场地为一处形状不规则的小型地块。依照业主需求，设计团队为其打造了一栋结合钢琴、小提琴与其他乐器的教室、演奏厅、专业录音设备店、乐器销售和储存空间以及管理各方业务的办公室的复合型建筑。

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.

因每层楼对隔音、景观、采光、遮阳以及使用时间的要求各异，且这些要求在未来发生变更的可能性极大。设计团队决定在项目中采用双层表皮，无论房间如何使用或窗户是否打开，都能保持统一的外观。材料方面则选择了一种可在高空摇摆的网状薄膜，可轻松向各个方向旋转，以获得最佳的天空视野，同时又能保持透光性及透气性。

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.

涂有PVC树脂的聚酯纤维防火外网膜，既能阻挡外界的视线，同时可让内部的人看到外面。其中33%的太阳反射率可使空调耗能降低28%。此外，这种薄膜还可以进行三维弯曲，轻量的材质加上穿孔图案，无论是从材料自重还是风压而言，均不会产生结构压力；继而，也不易产生坠落的风险，在此基础上，材料也可时常进行更换与维护，同时实现重复利用。疫情的影响大大增加了对于这种外墙的需求，在确保隐私的同时也可加强自然通风。

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.

过程中，设计团队考虑到该建筑不规则的地块形状，高度和退台的相关法规，还有如应急楼梯、阳台、管道和布线等必要元素，同时又要确保呈现的作品能展现该公司的身份象征。团队从各种乐器外观中获得了建筑形状的灵感，并对其进行了相应调整，以最大限度地提高容量。由网状结构覆盖的立面就像是一个传递音乐到附近社区的扬声器，而建筑也变成一个巨大的品牌标志，以实现宣传效果。

The form of the building takes into account 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.
