Moreover, the cultural elements in the station area are rich, then how design responding to the site elements is a proposition that cannot be avoided. The curved water-wave ceiling visualizes the illusion of Huangpu River above this metro line. These "waves" lap onto the columns, creating a rhythmic pulsation. --If the subway is compared to the arteries of the city of Shanghai, then at Yuyuan, the deepest station, it is as if you can feel the pulse of the city. These "waves" lap onto the columns, creating a rhythmic pulsation and an arcade.

The curvature of "wave tip" is extracted from Chinese eaves of the City God Temple. It subtly and implicitly echoes multiple cultural elements of the site. The plan of Yuyuan station is shaped to accommodate the track splitting and merging, and the distribution of ceiling pipes in the station hall is not homogeneous either. Therefore, the curved units cannot be simply repeated. Parametric design technology is adapted to generate forms and optimize the number of non-standard units on the basis of fitting to changes, in order to control the cost of mass production and installation.

The water wave ceiling is made of tens of thousands of aluminum panels, cut, bent and spliced. The ceiling system is combined with lighting to form a large three-dimensional LED canopy that can present a variety of light effects. It is able to present different lighting performances, according to different holiday events, Such as a China-Red for the National Day and the Spring Festival, Pink and flower petals for Valentine’s Day. While architectural spaces can be given soul by the sun's light, Yuyuan Station's underground space relies entirely on the flow of light from the ceiling.

This LED canopy can be opened to the public for submission, so that everyone can participate in shaping the spatial light and color of Yuyuan Garden Station. We also hope that Yuyuan Station will become such a canvas, where the public will continuously participate and infill various, colorful souls into it.
