Appreciation towards Low-Tech Lab (LOW) for providing the following description:


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.

▼竹桥外观,the exterior view


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.

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.

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.
