for providing the following description:

项目位于浙江省余姚市鹿亭乡。余姚是长江流域最古老的人类文明河姆渡的发源地，中村地处余姚四明山的原始次生林脚下，一条小溪穿流整个村落。在场地的岸两侧分别是乡伴树蛙部落的生态树屋和其配套的俱乐部，两者间需要一座桥的连接。甲方也提出了，工期短，低造价，使用年限大于三年即可的设计条件。不仅仅是形式，在设计中，材料，施工，造价也都是我们的考虑因素。

Situated at bottom of Siming Mountain in Zhongcun Village, Yuyao, Zhejiang, where Hemudu, one of the oldest civilization in the human history, originated. The villiage is seperated by a rivulet, along which TreeWow development, an ecological primtive treehouse resort, distributes. A pedastrian bridge in between is needed. The requirment from the client for the bridge is to be coherent with the primitive and ecological theme, and at the same time, with low budget and short construction period. Structure, construction and budget are considered as parameters throughout the design process.

在这里，竹材资源非常丰富，也曾有不少经验丰富的竹匠，但现在都已是简单粗暴的加工方式。村中的竹匠也大都外出务工或是上了年纪。因此，在解决功能需求的基础上，我们希望通过与当地老匠人一起，采用低造价，低环境影响的方法，建造一座纯竹结构的人行桥。因为最终施工将由当地工匠负责，所以我们将他们的经验也融入了设计的初始阶段。我们拜访了当地84岁的的竹匠，俞国治师傅，并提出了想要造一座竹拱桥的想法，俞师傅用图和模型表达了他的做法。

The site is abundant with bamboo and once many skilled bamboo artisans in the village. To rivive the perishing bamboo craftsmanship, the design is revolved around the use of bamboo, structurally and decoratively. Bamboo is a very sustainable and resilient material. However, it is rarely used in the modern construction because its non-standardized size and joints, unlike wood. To fully explore the potential of bamboo, artisan’ knowledge is included into the design process in the beginning. The local artisan, eighty-four-year-old Mr. Guozhi Yu partook a crucial role in the initial phase of design to fully inform the design team of the construction details. Because of the different accents, the profesionally-trained architecture team of LOW and the expeirence-based artisan communicated majorly through drawings and models.

围护同样采用了竹子，形式上强调结构的拱形，上下对称的形式则是受到当地白云桥和水中倒影的启发。当人们穿过竹桥时，逐渐升高和降低的围护将会将人们的视线导向不同的风景，远山，近水和过桥之后的树屋。

The project integrates modern aesthetics in the minimal form of the railing and inherited bamboo craftsmanship in the elaborate bamboo arch structure. The form of the railing is inspired by the image of the thousand-year-old stone arch bridge, White Cloud Bridge and its reflection in the water, the elegance and serenity of it. The form is also defined by human experience. As visitors crosses the bridge from one side to another, the eyes follow the railing, being guided to different views: the mountain in the distance, the rivulet under the bridge and the treehouses in the end.

▼竹桥概念来自当地另一座桥，the concept comes from an existing bridge

低技术实验室致力于提供系统性的设计方案，这意味着使用当地的材料，结合当地工艺的低技术施工方法，和适用于当地的设计方案，结合材料，结构及施工一体的设计流程，使得我们可以得到最经济适用的设计。中村竹桥的建造在25天内完成，仅花费2.6万元，其中5000元材料费，2.1万元人工费。

Low-Tech Lab (LOW) offers an sysmetic solution for modern rural construction and explores the design method that integrates material, structure and construction. As the result, the cost and construction period is reduced to the minimum. The bridge was constructed in 25 days and only cost 26000 RMB (approximate 3700USD), 5000 RMB for material and 21000 RMB for labor.
