南溪树屋的基本单元以银杏叶为原型，结构形式类似叉状脉，由根脉出发向外均匀分散，承托起扇形的平面。植物叶片上下之间适当错开，以获得更大受光量，树屋借鉴其 做法，在不同高度设置了错落有致的客房单元。客房均朝向主要景观面，但角度各不相同。各单元的结构和空间相互独立，既使整体造型呈现了自然有机的状态，也避免了 各单元之间因大悬挑钢结构产生颤动而互相干扰。树屋的主体框架由三根钢柱和主梁构成，形成稳定的三角形，承载了建筑的大部分荷载。叶脉状的一丛结构柱对悬挑底板 起到了重要的支撑作用，它们组成的扇形底面、屋顶的扇形斜面以及二者之间的小尺寸钢柱（包括窗框）共同形成了悬浮的结构单元。整个结构体系就像一株植被，树干扎 根于大地，而枝叶伸向苍穹。
The basic unit of Nanxi Tree House is modeled after ginkgo biloba, and its structural form resembles a forked vein, which is evenly dispersed outward from the root vein, supporting a fan-shaped plane. Similar to the proper staggering of the top and bottom of the leaves to allow for maximum light reception, the treehouses are arranged in staggered guest rooms at different heights, broadly facing the main landscape but at different angles. The structure and space of each unit are independent of each other, which not only presents a natural and organic state, but also avoids the interference caused by the slightest fluttering of the large cantilever steel structure. The tree house as a whole is framed by three steel columns and main beams, forming a stable triangular structure that carries most of the load of the whole building. A cluster of leaf-veined structural columns plays an important role in supporting the cantilevered floor, and its fan-shaped base and the fan-shaped slope of the roof, as well as the small steel columns (including the window frames) in between, form a suspended structural unit. The whole structural system is just like a tree. The trunk rooted in the earth, and the branches and leaves stretching out into the sky.
