浮在半空的楼板：断开一层楼的桥式办公楼

Design a commercial headquarters in the manner of Marcel Breuer as two stacked volumes separated by a completely open storey, the upper office block bridging across empty air on two concrete cores so the sky is visible straight through the gap. Compose the upper block clad in deep precast concrete window frames, the lower showroom podium in the same module, the void between them left entirely unfilled, a wide asphalt apron and highway edge, flat white overcast light, straight-on view emphasising the gap, 50mm lens, architectural photography, ultra photorealistic, 8K
