架构师提供的文本描述。使用螺旋是给出不同的方式“开放”和“关闭”之间的底层和上层：底层回到庭院，略低于地面，而上层面对开放的景观。螺旋两侧的内部楼梯完成了空间圈的系统，提供了在“开放”和“封闭”之间不断交换的完整体验。不同楼层的交替空间加强了以视觉形式观看的不同方式。在这里，观看的方式正是使用建筑物的方式。

Text description provided by the architects. Using a spiral is to give the different ways of “open” and “close” between the ground floor and upper floor: the ground floor is back towards the courtyard and slightly lower than the ground, while the upper floor faces outward to the open landscape. And the interior staircases on the both sides of the spiral accomplish the system of the circle of spaces, which also provide the complete experience of a constantly commutative cruise between the “open” and “close”. The alternate space of the different floors strengthens the different ways to view in a visual form. Here, the way to view is exactly the way to use the building.
