飞鸟亭位于苏州河南岸乌镇路桥和新闸路桥之间，建在一处半地下倒班房的屋顶平台之上，平台下是开阔的小广场和亲水驳岸，独特的位置使其成为滨河空间的“制高点”。初到这里，站在平台之上，苏州河从脚下静静流过，举目四望，视野极佳，令人印象深刻。因此，保留倒班房原有结构，存续原先场地高度成为了有利的设计条件。平台上原先有一个张拉膜结构凉亭，四根斜钢柱穿过结构顶板连接地下基础。作为滨水空间的景观小品，原有膜结构凉亭停留性差，体量不足以成为小广场的空间背景，也难以满足“制高点”对识别性的要求。

Flying-Bird Pavilion is located between Wu Zhen Road Bridge and Xin Zha Road Bridge at the southern bank of Su Zhou River. It is built upon the roof of a half-underground equipment office. There is a small piazza before the platform. It thus makes the site top of this waterfront space. When we first arrived here, standing on the platform, the Suzhou River flows quietly from the foot. We looked around and had an impressive view. Therefore, it is a favorable design condition to retain the original structure of the equipment office as well as the original site height. There was a tensile membrane structure Pavilion on the platform, and four inclined steel columns passed through the roof of the structure to connect the underground foundation. As a landscape sketch of waterfront space, the original film structure pavilion has poor retention, and its volume is not enough to become the space background of small piazza, and it is difficult to meet the requirements of “commanding height” for recognition.

对凉亭的改造起于对场地的梳理：休息平台与两条平行于河岸的漫步道相通，同时又通过两端的大台阶分别与东侧的小广场及南侧的跑步道连接，面积不大的平台却交织了这样多的通行需求，如何在其中创造出一个安静的观水休憩空间是首先要解决的问题。将原先四根斜柱裁切到人们落座的高度作为新结构支撑，依其定位阵列出沿弧线排开的铝结构单元，这样一道弧线就划分了场地内外。弧线外侧分离出供通行的漫步道，弧线内侧则自然形成了一个半包围的休憩空间。

The transformation of the pavilion starts from the arrangement of the site: the rest platform is connected with two walking paths parallel to the river bank, and at the same time, it is connected with the small square on the east side and the running path on the south side through the large steps on both ends. However, the small platform interweaves with so many traffic demands. How to create a quiet water viewing and rest space is the first problem to be solved. The original four inclined columns are cut to the height where people sit as the new structural support. According to their positioning array, the aluminum structural units are arranged along the arc line, so that an arc line divides the inside and outside of the site. The outer side of the arc separates the promenade for passage, while the inner side of the arc naturally forms a semi enclosed rest space.

铝结构单元继续向内向上生长，放大聚合成了雨棚，为这片小天地遮风避雨，人们落座于结构单元“缝隙”之间，面水而观，谈笑风生；铝结构单元向外向下蔓延，围绕出了漫步空间，台下的爬藤顺着延展的铝条向上攀爬，包裹出一条绿荫小道，人们游走其中，捕捉藤叶间的斑驳。而连接内外的铝结构单元，自身也变成了充满韵律感的“隧道”，成为了小朋友嬉戏玩耍的小天地。这样一个长度达14米的全铝结构整体，重量完全承托在原先的四根线性排列的斜柱之上，雨棚向上往河边悬挑，铝条向下通过栓接轻巧地搭在平台的边沿，整体维持着巧妙的平衡，铝结构自身的金属光泽在粼粼波光的映衬下熠熠生辉。 沿着河边漫步道走来，远远看去，如同羽毛般的结构韵律，如悬浮般的体量支撑，新的凉亭像是银色丝带织成的小鸟，在苏州河岸边振翅待飞，身姿轻盈，向水而生，因此而名-飞鸟亭。

Aluminum structural units continue to grow inward, and enlarge and aggregate into a canopy to shelter the small world from the wind and rain. People sit between the “cracks” of the structural units, watch and laugh in the face of water; aluminum structural units spread outward and downward, surrounding a walking space, and climbing vines under the stage climb upward along the extended aluminum strip, wrapping a shady path, where people walk and catch the mottle between the leaves of rattan. The aluminum structural unit connecting the inside and outside has become a rhythmic “tunnel” and a small world for children to play. The weight of such a 14m long all aluminum structure is completely supported on the original four linearly arranged inclined columns. The canopy is overhanging up to the river, and the aluminum bars are bolted down to the edge of the platform. The overall balance is maintained ingeniously. The metallic luster of the aluminum structure is shining against the sparkling light. Walking along the riverside promenade, you can see from a distance that the structure rhythm is like feathers, and the volume support is like suspension. The new pavilion is like a bird woven with silver ribbon, flapping its wings and waiting to fly on the Bank of Suzhou River. Its body is light and living towards the water, so it is called “Flying Bird Pavilion”.
