该项目位于浙江省余姚市思明山脚下一个很少有人参观的山村。这个村庄坐落在次生林的边缘。一条小河，把村子分成两部分，从北到南缓缓流过。树屋位于下游西岸。两座山峰相望，分别矗立在景区的东侧和西侧，青翠的竹子散落在山上，营造了一种和蔼可亲、宁静的气氛。

Site The project is located in a rarely visited mountain village at the foot of the Siming Mountain in Yuyao, Zhejiang Province. The village rests on the edge of a secondary forest. a small river, dividing the village into two parts, slowly runs through from north to south. The tree house is located on the west bank of the lower stream. Two peaks facing to each other are standing on the east and the west sides of the site, where verdant bamboos are spread all over the hill, creating an amiable and tranquil atmosphere.

树屋高8米，大致相当于成年竹子的高度.它分为上下两部分。下部由钢支撑柱组成，上部以木结构为主。树屋位于堤坝的一侧，周围是古老的竹林，对面是小溪对面的老茶厂。露台的一部分悬挂在溪流之上，形成了漂浮的感觉。此外，由于钢柱在陆地上缩成几个点，以尽量减少对环境的影响，因此产生了更大的地面活动自由空间。

The tree house is 8-meter high, roughly equal to the height of an adult bamboo. It is divided into upper and lower parts. The lower part is composed of steel supporting columns; while the upper part is mainly wood structure. The tree house is located on one side of the dyke where is surrounded by ancient bamboo forests while facing the old tea factory across the creek. Part of the terrace is hanging over the streams, creating a sense of floating. Moreover, since the steel columns are huddled to several points on the land to minimize the impact on the environment, larger free space for ground activities is produced.

概念的过程

平面上的木质部分由三个非同心圆组成：溪流之上的露台，两层客房，以及起伏的屋顶和露台。这个计划是一条简单的螺旋线。一个圆形的外墙被整合到内部，将浴室和台阶与起居空间分开，进入阁楼。每一扇窗户都有一个独特的外景，但最好的部分是爬上屋顶，欣赏山的自然魅力。

Plan The wooden part in upper level consists of three non-concentric circles: the terrace overhanging the stream, the two-story guest room, and the undulating roof and terrace. The plan is a simple spiral line. A circle of the outer wall is integrated into the interior, separated the bathroom and the steps into the mezzanine away from the living space. Each window has a unique view to the outside, but the best part is to climb to the top of the roof and enjoy the natural charms of the mountains.

结构、屋顶和墙壁的特点是由57根巨大的桁架支撑，这些桁架的厚度逐渐变化。表面上柔软的屋顶不仅有助于勾勒出优雅的天际线，更重要的是，飘荡的屋檐从窗户将景观引入房间，并保持了房间的隐私。

Features of the Structure The roof and the walls are supported by fifty-seven giant trusses that vary gradually in thickness. The ostensibly soft roof not only helps outlining the elegant skyline, more importantly, the waving eave introduced the landscape into the room from the window and kept the privacy of the rooms.

传统民居的屋顶的功能不同于在标准化和工业化下的精细生产。波动的屋顶不是建筑师的任意幻想。非线性屋檐具有极高的容错率，可作为农村建设对自然规律的尊重。在设计和施工过程中，建筑师与当地工匠保持密切联系，以实现设计形式与当地施工技能之间的平衡。

The Functions of the Roof The crude hand construction of traditional dwellings is different from fine production under standardization and industrialization. The fluctuating roof is not an arbitrary fantasy of the architect. The non-linear eave has extremely high error-tolerant rate, which can be considered as a respect of rural construction to natural laws. During the design and construction process, the architect remained close communications with local craftsmen to achieve a balance between the design form and local construction skills.

屋面的变化决定了内外之间的视觉交流，以及从私人到公共空间的连续梯度。当客人进入一楼的露台时，他们将开始体验从阳台到相连的室内的圆形空间序列：从客厅到巨大的窗户，到大深度的露台，再到展开的屋顶，欣赏小溪和竹山的景观；从卧室到低矮的窗户，再到落下来的屋顶，在躺着的时候能看到好的景色。

The changes of the roof defined the visual communications between the inside and the outside as well as the continuous gradient from the private to the public spaces. When the guest enters the terrace on the first floor, they will start to experience the circular sequence of spaces from the eave along the terrace to the connected interior: from the living room to the huge window, to the terrace of large depth and to the unwrapping roof to enjoy the view to the creek and the landscape of the mountain of bamboos; from the bedroom to the low window, to the falling roof to capture a good view when lying

开放的浴缸和一侧的高窗保证了隐私以及对自然景观的满足，浴室入口处的垂直窗口被屋顶完全覆盖，确保了绝对隐私而不影响自然通风；沿着螺旋楼梯走到二楼，人们可以坐在露台周围，在起伏不定的屋顶上看到那棵将近两百年历史的老树。体验之旅在二楼的屋顶上的露台上结束，人们可以在那里享受一口茶，同时又可以被群山环绕。

The open bathtub and the high window at the side guaranteed the privacy as well as the satisfaction of views to the nature; the vertical window at the entrance to the bathroom is completely covered by the roof, ensuring absolute privacy without affecting natural ventilation; walking along the spiral staircase into the second floor, people can sit around the terrace and see the old tree which is almost two hundred years old through the fluctuating roof. The journey of experience ends at the terrace enclosed nu the roof at the second floor, where people can enjoy a sip of tea while being surround by the mountains.
