Throughout the design process, the biggest challenge was the construction of the facade. The initial attempt was to use stainless steel to create a texture close to aluminum, but it turned out unsatisfactory. After multiple tests, the design team finally decided to take aluminum plates as the main materials. As aluminum plate is too soft, it needed polishing before being installed on the wall. The task was demanding but a desirable result was realized at last.

Aluminum plates take on different textures as time goes by. The natural oxidation captures the trace of time, and the uncertainty of nature leaves its beautiful print on the architecture which gradually fits in with nature.
