壮大なリングの中庭：屋上のランニングトラック

Design a city block in the manner of Liu Jiakun's West Village Basis Yard — a single hollow perimeter building occupying a whole block, its interior left as an enormous public courtyard with sports fields, and a continuous ramped jogging track running around the roof and through the building. Compose a five-storey ring of bamboo-formed concrete enclosing a vast green court, a continuous elevated ramp climbing across the facade and around the roofline, people running on the ramp and playing below, plants spilling from the galleries, humid Chengdu light, elevated three-quarter view, 24mm lens, architectural photography, ultra photorealistic, 8K
