架构师提供的文本描述。这是一个长方形的地段，两边都是相邻的多层房屋。因此，设计上的挑战是将自然光带到底层，并在一小块地内创造一个宽敞的居住空间。

Text description provided by the architects. The site is a rectangular lot whose sides are occupied by neighboring multi-story houses. As a result, the design challenges are to bring natural light to bottom floors and create a generous space for living within a small lot.

我们通过划分程序开始设计：一边是楼梯和走廊这样的循环元素，另一边是主要的生活功能。接下来，我们建议将程序分成一边的墙折叠起来，以解决上述挑战。

We started the design by dividing up the program: circulation elements such as stairs and hallway on one side and main living functions on the other. Next, we proposed to fold the wall that divides the program to one side to solve the aforementioned challenges.

纵向第2节

只需将墙壁向一侧折叠，循环空间就会缩小，从而增加顶层卧室的可用空间。折墙产生的倾斜表面会从上面扩散进来的自然光，每过一小时就会使室内充满不同的照明条件。

By simply folding the wall towards one side, the circulation space is narrowed, thereby increasing usable spaces for the bedrooms on the top floors. The sloping surfaces generated by folding the wall diffuses natural light coming in from above, filling the interior with different lighting conditions as each hour passes.

这种折叠墙的结构执行比传统结构要复杂得多，费用也高。幸运的是，我们得到了客户的认可和合作，才能将设计变成现实。

The structure execution of this folding wall is relatively more complex and expensive than that of conventional structures. Fortunately, we have the approval and cooperation of clients in order to turn the design into reality.
