The project is located in the core area of Shanghai Hongqiao Business City, adjacent to the transportation hub, and is a landmark building of Bosideng’s global headquarters, carrying the brand’s international image. Taking inspiration from the lightness and warmth of down, the tower crown linear lighting simulates the “energy particle flow” (daily 4000K/festival dynamic RGBW), and the tower body flying wing design adopts side wash lighting technology to reproduce the soft texture of down, echoing the brand’s 48 year heritage of craftsmanship. Using light as the feather, linking the physical warmth of down with the imagery of cosmic energy, shaping the brand spirit totem of “technology warmth coexisting” at the Hongqiao hub.
