The “Xiangjiang Eye” is located along the Xiangjiang River in Changsha, serving as both a city reception hall and a landmark. Inspired by lotus flowers, its unique feature is a movable roof that can rise and fall, ensuring panoramic views without blocking surrounding buildings. The exterior can open and close like petals, creating either open or private spaces. The structure uses low-transparency ETFE membrane for its outer petals, enhancing the dynamic design and natural ventilation while balancing commercial value and urban aesthetics.
