巨梁下的无柱公共厅：诚实结构与自由使用

Design a contemporary public interior inspired by Paulo Mendes da Rocha. Create expansive column-free halls beneath monumental exposed concrete beams with generous daylight, natural cross ventilation, and minimal partitions. Express structure honestly while allowing flexible civic activities, exhibitions, and public gatherings to occupy the space naturally. A hall spanned by four enormous board-marked concrete beams carrying the roof so the floor is entirely free of columns, open sides with no glazing letting breeze pass through, a plain concrete floor with an exhibition and a group of people sharing the space, harsh tropical daylight from the open ends, wide one-point perspective, 24mm lens, interior photography, ultra photorealistic, 8K
