幾何学と虚空：三角形と円形アトリウムの減法的彫刻

Design a contemplative cultural building inspired by Tadao Ando using subtractive geometry, monolithic concrete volumes, triangular and circular courtyards, and silent spatial sequencing. Emphasize emptiness, proportion, and the emotional power of natural light. A solid concrete block from which a triangular court and a circular court have been cut away, no windows on the outer faces, ramps descending between the two voids, smooth formwork with regular tie holes, hard midday sun making the void geometry razor-sharp, elevated three-quarter view, 28mm lens, architectural photography, ultra photorealistic, 8K
