2019-2020年深港城市建筑双城双年展（Bi-City Biennale of Urbanism╱Architecture, UABB）以城市交互（Urban Interactions）作为展览主题，透过时间与空间试图寻找未来发展的新可能性。深圳也因先天性独特与多样的地理资源，城市居住者可以在一天的时间中体验山丘与海滩，这样包容著两种自然景观的介面城市，让居民得以感受到自由、自在与瞬时等可能性，位于大鹏新区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.

溪涌度假村因环山围绕，视觉景观向海岸线开放，进而让此区域成为观察自然变化的容器；因此设计的重点并非再建立一个新构筑物，而是如何创造“看与望”的景观方式来呈现日常场域。项目原场地是个半弧形观景台，竖立著粗重的栏杆与冰冷的混凝土地面，阻隔人与海的活动；建筑操作以竖向线条强调厚实与隐蔽，重新定义栏杆与海的介面，再以水平线条围塑平滑与清透的空间，从而创造一个与海互动或对话的舞台。

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.

在进入琴亭前，访客透过高低和间距不一的围篱，从而感受到与海景的距离感，衍生对景观万物的珍惜与呵护；进入到琴亭内，透过曲线场地围塑出优美形状的绳索，自然光影的撒落与风声吹拂的韵律，从中感受到环境事物的多样与丰富。设计以坚固钢板和轻柔绳索结合特殊的张拉结构型式，并以沙丘与石块作为场地内景观特徵，来呈现溪涌最重要的在地性──硕大高山林、浮动海岸线。

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.
