中國廣東省 大沙河生態長廊環形樹屋
The Serpentine Bookhouse is located amidst the greenery of trees along the Dasha River Ecological Corridor. To its west, the 13-kilometer scenic pathway of the Ecological Corridor runs continuously, and the north side is close to a children's park with enjoyable sand pits attracting many family visitors, while the east side is surrounded by dense residential communities. The newly added public building includes a children's reading room of 300 square meters and a public restroom open to park visitors 24/7, serving local residents and visitors starting from the fall of 2022.
The traditions and folklore of fishermen along the Dasha River inspired the architect with the design concept of a "spiral conch". The building performs like a rising spiral art sculpture, returning as much ground space as possible for plant growth and tourist activities. The end of the spiral volume faces the riverside park with an open balcony, providing visitors with a place to relax at the height of the treetops. Therefore, it is named "Serpentine Bookhouse" by the locals.
地處大沙河生態長廊沿岸綠樹掩映叢中，環形樹屋西側緊臨全長 13 公里的大沙河沿岸景觀步道西麗段，北側靠近兒童公園，東側被密集的住宅社區環繞。這座新建的公共建築功能包括一座約 300 平方公尺的兒童主題書房，與全天對公園遊客開放的公共廁所，其自 2022 年秋天開始服務周邊市民及到訪遊客。
大沙河沿岸的早期漁民傳統賦予建築設計師以「海螺」為原型的設計靈感。本案宛若一座螺旋上升的藝術雕塑，盡可能將地面空間歸還植物與遊客。盤旋體的底端以開放式陽台面向河岸公園，提供遊人一個在樹梢高度的休閒場所，因此也被在地居民稱為「環形樹屋」。
Following the exterior form of the building, the interior space presents itself as a series of stepped reading spaces winding around the trees in the atrium. At the same time, it offers a panoramic view of the park landscape through floor-to-ceiling windows.
The stepped reading spaces with rich height differences provide an opportunity for children to explore and satisfy their natural curiosity and cultivate their interest in independent learning. The slide is open to children every day after school, which will add a fun and exciting dimension to the space.
In response to the hot climate in Shenzhen, continuous vertical grilles are installed as sunshade devices on the facade of the building, which also brings a changing light and shadow experience to the interior space over time. Operable windows are installed on each reading step, and on the second-floor balcony, sliding doors can be fully opened to ensure natural ventilation and to achieve satisfactory comfort in autumn and winter seasons without using air conditioning.
The challenging structure of the building is achieved with steel framework. The inner and outer circles use spiral Vierendeel trusses to determine the arc shape, and the large cantilever of the viewing balcony on the second floor is supported by oblique tension enforcement. All major structural components are shipped to the site for assembly after prefabrication in the factory, minimizing the disturbance of the site construction to the park and nearby residents' lives.
順應建築外觀，樹屋的室內空間呈現繞著中庭樹木螺旋上升的閱讀階梯，同時透過落地窗得以遍覽外側公園風景。據高低差的階梯式閱讀空間可以釋放孩子們的天性、激發好奇心和探索欲，培養其自主學習的興趣。而溜滑梯於放學時段開放，為整體空間增添趣味。
對於深圳炎熱的氣候環境，建築外層採用了連續的垂直格柵作為遮陽裝置，這為室內空間創造出隨時間變化的光影感受。同時在閱讀階梯每一處都對應裝設活動窗，並於二層陽台設置了可以完全打開的推拉門，保證在秋冬季節僅憑自然通風能夠達到令人滿意的舒適度。
環形樹屋極富挑戰性的結構採用鋼結構形式，內外圈運用范倫迪爾桁架系統確定弧狀外型，二樓觀景陽台的大懸臂則使用斜向拉力支撐。所有結構構件在工廠加工完成後運至現場拼裝，將現場施工對公園和居民生活的干擾降低到最小程度。
The Serpentine Bookhouse embodies the urban revitalization strategy that Shenzhen has been pursuing in recent years. In the goal of adding small-scale civic and cultural buildings to serve public life in the parks and public spaces, this strategy helps public projects land in a timely and accurate manner with a relatively small investment and relatively short construction time. With the joint efforts between design and construction teams, the Dasha River Serpentine Bookhouse project was completed and put into use in less than one year from design to construction. Since its opening, it regularly holds art exhibitions and reading clubs, thus becoming one of the favorite spots for urban dwellers and especially family visitors to escape from the stresses of urban life and to commune with nature and fellow cultural communities.
環形樹屋體現了近年來在深圳各級公園及公共空間營造，以增加小型公共建築服務公共生活的城市活化策略。這一策略可以用相對小的投資量體和相對短的建設時間幫助公共建設項目即時準確落地服務公眾。在設計、施工諸多單位的共同配合下，大沙河環形樹屋從設計到施工完成，僅用時不到一年的時間。自開放以來，這裡定期舉辦藝術展覽和讀書會，成為周邊市民遊客——特別是孩子們喜愛的場所。
