2019-2020年深港城市建築雙城雙年展（Bi-City Biennale of Urbanism╱Architecture, UABB）以城市交互（Urban Interactions）作為展覽主題，透過時間與空間試圖尋找未來發展的新可能性。深圳也因先天性獨特與多樣的地理資源，城市居住者可以在一天的時間中體驗山丘與海灘，這樣包容著兩種自然景觀的介面城市，讓居民得以感受到自由、自在與瞬時等可能性，位於大鵬新區的溪涌度假村正是最好的例子。

The 2019 Bi-City Biennale of Urbanism╱Architecture (UABB) uses Urban Interactions as the theme of the exhibition, aiming to explore new possibilities for future development through time and space. The city of Shenzhen is also congenital with unique and diverse geographical resources, where urban residents can experience the cliffs and coasts in one day. By containing two natural sceneries in one city, it provides residents an experience of openness and freedom, with the Xichong Resort in Dapeng New District as the best example.

溪涌度假村因環山圍繞，視覺景觀向海岸線開放，進而讓此區域成為觀察自然變化的容器；因此設計的重點並非再建立一個新構築物，而是如何創造“看與望”的景觀方式來呈現日常場域。項目原場地是個半弧形觀景臺，豎立著粗重的欄杆與冰冷的混凝土地面，阻隔人與海的活動；建築操作以豎向線條強調厚實與隱蔽，重新定義欄杆與海的介面，再以水平線條圍塑平滑與清透的空間，從而創造一個與海互動或對話的舞臺。

Surrounded by mountains, the visual landscape of Xichong Resort is open to the coastline, thus making this region a vessel for observing natural changes; therefore, the focus of the design is not to build a new structure, but to create a scenery lens to present daily views. The original site of the project is a semi-arc viewing platform, with heavy railings and cold concrete ground, blocking the interaction of people and the sea. The new construction operation emphasizes solidity and concealment with vertical lines, redefining the interface between the railings and the sea; horizontal lines enclose a smooth and clear space, creating a platform for interaction or dialogue with the ocean.

在進入琴亭前，訪客透過高低和間距不一的圍籬，從而感受到與海景的距離感，衍生對景觀萬物的珍惜與呵護；進入到琴亭內，透過曲線場地圍塑出優美形狀的繩索，自然光影的撒落與風聲吹拂的韻律，從中感受到環境事物的多樣與豐富。設計以堅固鋼板和輕柔繩索結合特殊的張拉結構型式，並以沙丘與石塊作為場地內景觀特徵，來呈現溪涌最重要的在地性──碩大高山林、浮動海岸線。

Before entering the pavilion, visitors pass through fences of different heights and spacings, thereby perceiving the distance from the seascape, which cherishes and nurtures for the scenery. As entering the pavilion, the strings form an artistic scene through the curvilinear site, the scattered natural light, shadow, and the sound of wind together present a rhythm, providing an experience of the diversity and richness of the environment. The design employs sturdy steel plates and delicate strings in combination with a special tensile structure. Moreover, the sand dunes and stones are used in creating an interior landscape to present the most significant regional characteristics of the Xichong—vast mountain forests and floating coastlines.
