解放地面层：结构集中于上方公共广场

Design a large corporate building that liberates the ground level as an open civic plaza while concentrating structural systems above. Prioritize pedestrian continuity and urban openness inspired by Norman Foster. The entire ground floor left open with no walls or lobby, only a few massive supports touching the ground, the building mass beginning one storey up, pedestrians crossing straight through the site, deep shade beneath the mass, hard urban light, eye-level composition, 24mm lens, ultra photorealistic, 8K
