架构师提供的文本描述。这种建筑有两个功能：一个糖果店和一个音乐厅。无论是外部还是内部，都可以根据这两种不同的功能以及声学来改变它们的氛围。换句话说，这个建筑有一个“双面脸”。此外，由于北海道是一个领先的林区，客户希望在室内设计中使用木材来提高商店的形象。

Text description provided by the architects. This architecture possesses two functions: a confectionary shop and a concert hall. Both exterior and interior can change their atmosphere according to the two different functions as well as acoustics. In other words, this architecture has a “double face”. Also the client wanted use wood for the interior design to enhance the image of the shop, since Hokkaido is a leading forestry area.

主要关注的是声学的有效性。木材是极好的声音反射板。因此，利用本地木材设计了声反射器。当它被用作音乐厅时，混响时间就会变长。另一方面，当用作糖果店时，混响时间必须缩短。在这个项目中，独特的想法，如墙上的可移动挂毯和从天花板上悬挂的反光襟翼，克服了这种担忧。在短短三个小时内，家具必须重新安排，当这个建筑改变其面貌从一个功能到另一个功能。

A major concern is the acoustic effectiveness. Wood is excellent as a sound reflecting board. Therefore, sound reflectors were designed using the local timber. When it is used as a concert hall, the reverberation time becomes long. On the other hand, when used as a confectionary shop, the reverberation time has to be shortened. In this project, unique ideas such as movable tapestries on the walls and reflective flaps hanging from the ceiling overcome this concern. Within only three hours, furniture must be re-arranged when this architecture changes its face from one function to the other.
