This case is located on the southwest side of the Hunan Garden community on Gandao Island. The design starts from spatial experience, and the runway is horizontally arranged in a circular shape to connect the outdoor space, atrium, corridor, roof activity platform, and other spaces. The atrium, ramp, and scattered activity spaces such as skylights, steps, and stairs on the roof activate the atmosphere of the park. The flowing spatial layout provides a free and inclusive spatial atmosphere. Empower the space with infinite possibilities and usage scenarios, creating a connected public space for children, blurring the differences between floors, blurring the boundaries between indoor and outdoor spaces, and blurring the single use of the space.
