Tianhu Lake Lodge is situated within the core area of Tianhu Lake on Yushan Island, renovated from the original reservoir management building, standing by the lake with exceptional views. Tianhu Lake is not only a natural wonder but also a vital freshwater reservoir essential to the island’s life and ecosystem. Due to its unique location, new construction is highly restricted. The original building was located precisely at the bus drop-off point, making its renovation a rare opportunity to create an indoor rest area along the 2.5km lakeside tourist route and to establish a new interactive dialogue between human and lake.
The renovated building combines reservoir management functions with public services. While retaining water monitoring equipment on the first floor and office accommodation for staff on the second, most of the ground floor is opened to the public as a resting, waiting, and tea/coffee area. A third-floor lakeside tea room was added. A key challenge was subtly concealing the service spaces within the visitor experience. The façade features a wall of reclaimed tiles, hiding the office corridor while allowing light and ventilation. The staircase to the second-floor office diverges early, blending discreetly into the path to the third floor.
The relationship between architecture, people, and the lake was carefully considered throughout the design. Inspired by the modest aesthetic of Fuding white tea, simple materials and forms create a Zen-like visitor space. Large glass doors on the ground floor guide visitors from land toward the water. An opened staircase includes a waterside platform on the first floor, bringing people closer to the lake. On the second floor, a branching staircase forms a lake-viewing terrace. To reduce the visual impact of the third-floor addition, a semi-arched profile was used, focusing views toward Tianhu Lake.
Tianhu Lake Lodge represents an attempt at infrastructure renovation. Beyond formal considerations, the focus was on enhancing public service quality through the adaptive reuse of a management building, seamlessly integrating functional and public spaces. This project encourages visitors to slow down, stay, and engage with the lake in new ways.
