园地分前后两个部分，前部是一块空地，包含两个砖房和一棵老树；后部是一个U形建筑体，玻璃屋顶挡住了内院。旧建筑构造老化，房间狭小封闭，短缺根本举动步伐，已经无法知足当代生活的利用，须要彻底改造。改造之后的建筑将出租给潜在的客户，须要知足可办公、可聚会、可居住的弹性利用。因此，本次改造的紧张寻衅是：如何基于现存条件做恰当的拆改，增加建筑空间的活力，回应不愿定的功能。

基于平屋顶建筑的特点，设计在旧有建筑平面格局上添加了连廊和楼梯，将屋顶与地面、房屋与庭院相互串联，成为一条可通达抚玩的折叠循环路线，让建筑的内与外、上与下、新与旧产生互动关系。

平屋顶是一处在四合院区域难得的公共活动园地，也是内部功能利用的主要延伸，屋顶景不雅观与周边繁芜多样的坡屋顶建筑和树木形成有趣的对应。

环绕折叠的环线，由入口向内部自然划分出四个不同尺度的庭院——入口处狭长的竹院；保留原有老槐树的树院；打消原来玻璃顶，并置入水景、卵石的水院；以及保留南向与邻里过渡的后院。因此，在这个空间游走将伴随着不断变革的景致。
Along the circulation route, four yards of different scales were marked out, including a long and narrow yard embellished with bamboos at the entrance, a yard with an old locust tree remained in situ, a yard characterized by waterscape and cobbles, with the original glass roof removed, and a south-facing backyard connecting to the neighbor’s house. By following the circulation, people can enjoy variable views in the space.

保留原有建筑的两处砖屋子，并新增三处砖盒子则作为私密空间，功能分别被设定为安歇室、厨房、卫生间等。盒子之间构成连续而又分离的公共区域，可容纳办公、聚会、餐饮等活动。砖盒子墙体内部隐蔽着屋面的构造，设计故意让屋面与砖盒子墙面脱开产生天光的缝隙，令二者独立并置。
ARCHSTUDIO retained the two brick rooms that already existed, and at the same time inserted three new brick-structured boxes, which were set as private spaces and can serve the functions of sitting room, kitchen, restroom, etc. The gaps between the three new boxes form a continuous but detached public space for working, gathering, dining and other activities. The architects hided structural columns of the roof inside the brick boxes’ walls, and deliberately left gaps between the roof and boxes, with a view to letting daylight filter in.

项目沿用了四合院常见的旧砖、青瓦、水泥等作为紧张材料。屋面均为立砌青瓦铺装，青瓦按照屋顶不同方向线性排布，并跟随楼梯连接到室内，产生如流水一样平常的视觉效果。屋面为现浇混凝土板，室表里面保留了木纹模板的自然纹理。砖盒子则是由附近院落拆除的旧砖砌筑的，由墙面延伸到屋顶并形成了安歇座椅。
Common construction materials for Siheyuan such as bricks, grey tiles and cement were utilized for this project. The rooftop was paved with grey tiles, which were arranged linearly in different directions. Notably, those tiles extend to indoor area, resulting in flowing-water-like visual effects. The roof has a cast-in-situ concrete structure, and wood grains on interior surfaces generated from the form work was retained. The brick boxes were built with old bricks from demolished houses nearby, with the wall stretching to the rooftop and forming seats for resting.
