Appreciation towards Ryo Otsuka Architects for providing the following description:

项目坐落于东京板桥区某住宅/购物区的拱廊尽头。场地周边有很多小住宅与有趣的小店铺，整体氛围宁静安详且充满怀旧之感。春天的时候，竹井河畔到处都是赏花的游人。建筑的形态由场地边界生成，它静静地伫立于后巷，完美融入于社区环境之中。作为一个小型的会员制音乐沙龙，Maly Koncert音乐厅既要保证与大型音乐厅相媲美的室内音质，同时也要考虑到噪音的问题，使音乐厅在密集的城市环境中做到不扰民。场地呈不规则的旗杆状，人流从“杆”状的通道进入建筑，而后自然地汇入室内的交通流线。此外，建筑内还设置了一个附属房间，以集成各种功能设施，如音响设备等。

The site is located at the end of an arcade leading from a quiet residential / shopping district in Itabashi-Ku, Tokyo. The surrounding area is very nostalgic, has many houses and small shops. In springtime, the Shakujii River is filled with people to see Sakura blossom. The architecture shape is formed by the shape of the site and merged into the neighborhood, standing quietly in the back alley. When planning a small membership-based music salon, you need to ensure the sound quality is the same as a large-scale music hall and, set a high noise control for the dense neighborhood. Natural circulation is created with the irregular flagpole-shaped site, entering the space from a “rod” shaped part of the site, and flows into it. The plan was to lift an attached room that integrates various functions such as sound equipment.

经典音乐空间
A Space for Classic Music

在规划阶段，建筑师常常扪心自问，“我喜欢什么样的空间来听古典音乐?” 答案很简单，那就是“高品质的音效，空间、音乐以及演奏者的高度融合”

In the planning stage, I often question myself, ” What kind of space would I like to listen to classical music?” And the answer turned out to be quite simple, I would like to make, ” Great sound effect, and space where music, musician and space and unite.”

乐器具有普遍的美，精致的音调与音乐家的演奏姿态将这种美进一步地升华。音乐厅作为表演的背景，其质朴的原材料与粗犷的纹理将人们的视线聚焦于演奏者身上，使人们自然而然地沉浸于音乐之中。现代的气息与古典的神韵在建筑中完美融合，如同一件优雅的乐器，音质会随着时间的推移越加深邃。

A musical instrument has universal beauty, and it is contrasted with the delicate sound and player’s action. Musical instruments have universal beauty, contrast with delicate tones, and performers’ actions. Space was constructed based on powerful and raw materials. The material helps to create a natural focal point on the musician and their performance. Aiming for an instrument-like space, that gets deeper over time; intended for modern classic architecture.

声学模拟主导的空间比例
Proportion of the Space led by Acoustic Simulation

在本项目中，空间的比例基于声学模拟数据，以确保声音能在有限的建筑高度内均匀地回荡在整个音乐厅之中。通常，当天花板、地板和墙壁平行布置时，会产生颤振回波，影响听众的声学感受。为了避免这种情况，建筑师在空间中增加了大量的声学板，以确保声音可以均匀地传递开来。建筑的平面根据场地的形态呈不规则的四边形，二层通高的演奏空间则采用了坡屋顶形式。这种设置不仅有助于实现均匀的音质效果，同时也能够将设备隐藏在倾斜的天花板与水平设备框架之间。

For the main music salon, the proportion of the space is designed based on the acoustic simulation, to ensure that the sound can evenly reverberate throughout the space within the limited building height. Normally, flutter echoes occur when the ceiling, floor, and wall are arranged parallel to one another. To avoid the flutter echo, numerous acoustic panels are added to ensure that the sound can spread evenly throughout. The plan and site are shaped as an irregular quadrilateral, and a square roof is adopted for the double height of space. Achieving a uniform acoustic effect, and is also practical for equipment to be placed under the sloped ceiling.

用声音为空间增色
“Reveal” and “Add” according to the sound

主要空间采用了无柱钢筋混凝土墙，以确保低音的回声。线性空间的设计充分利用了狭小的场地，进一步优化了整体噪音的控制，此外，室内设计也纳入了必要的设备区与缓冲区。充满力量的刚性建筑与柔和的音质效果为Maly Koncert音乐厅赋予了迷人的气质，营造出和谐且平衡的空间氛围。

The main space is designed to be pillar-free with reinforced concrete walls to secure the echo of base sound. Linear space is designed to make good use of the small site, to improve the overall noise control, necessary equipment and buffer zones are also incorporated to space. The space proportion is mixed of hardness and softness, hardness from the architecture, and softness from the sound effect, giving the space a balanced harmony.
