架构师提供的文本描述。位于北京胡同四合院(四合院)，是为一对夫妇和两只猫设计的租房改造方案。以前的四合院被称为“扎院”，是为了容纳几个不同的家庭而细分的。原有建筑物的改建和扩建逐渐占据了原来的公共空间，现在只留下一条通道。从扎远的西北角进入，经过那个狭窄的通道后，人们会在东南角找到这个项目(图1)。

Text description provided by the architects. Located in a courtyard (siheyuan) of hutong in Beijing, this is a rental housing renovation plan designed for a couple and two cats. Known as zayuan, the previous courtyard was subdivided in order to accommodate several different families. Modifications and extensions to the original buildings gradually occupied the once public space, leaving only a passage now. Entering from the northwest corner of the zayuan, one finds the project at the southeast corner after passing through that narrow passage (Figure 1).

在一个只有19平方米的空间里，建筑师解决了撒园常见的问题，如确保通风和照明，减少拥挤的环境所带来的不安。

In an only 19m2 space, the architect has dealt with the common problems of zayuan, such as ensuring ventilation and lighting, reducing the uneasiness the cramped environment engendered.

建筑师保留了原来的屋顶，拆除了其余的屋顶。北墙和南墙分别开放，以确保通风和照明。一半的盒子形状的空间和一层地板被嵌入，以扩大生活空间。

The architect kept the original roof and removed the rest. The north and south walls were opened respectively to ensure ventilation and lighting. Half of a box-shape space and a layer of floor were embedded to extend the living space.

如图所示，二楼发挥私人功能，利用提高的高度来保证隐私；一楼发挥相当的公共功能，最大限度地扩大外墙的开放性。庭院通道形成了一个通畅的空间，穿过室内空间的第一层，延伸到南院。通过视觉上的共存，一楼的过道和扎院的通道成功地避免了室内与室外的二元概念，有效地减少了扎远通常造成的不安。

As the plan shows, the 2nd floor performs the private functions, which uses the raised height to guarantee privacy; the 1st floor performs the rather public functions, maximizing the openness of the exterior wall. An unobstructed space was created from the courtyard passage, running through the first floor of the interior space and extending to the southern yard. By coexisting visually, the aisle in the first floor and the passage of the zayuan successfully avoid the binary conception of indoor vs. outdoor, effectively reduced the uneasiness that zayuan usually causes.
