无柱大厅：悬挂屋顶下的通用空间

Design a column-free hall in the manner of Mies van der Rohe, where a deep coffered steel roof is carried on eight perimeter columns so the entire interior is unobstructed. Compose a black steel waffle ceiling overhead, glazing on all four sides with only slim mullions, a granite floor, temporary exhibition partitions standing free without touching the ceiling, the park visible through every wall, cool even daylight, wide one-point perspective across the empty hall, 24mm lens, interior photography, ultra photorealistic, 8K
