纯几何的精神性建筑：看不见的结构体量

Design a minimalist cultural or spiritual building inspired by Tadao Ando using pure geometric volumes, flawless exposed concrete, invisible structural systems, framed nature, and silent spaces that encourage contemplation and emotional reflection. A pure cylinder intersecting a rectangular volume, seamless concrete with no visible joints or downpipes, a narrow processional approach along a blank wall, one framed opening at the end of the axis, calm overcast daylight, wide gravel foreground, eye-level composition, 24mm tilt-shift lens, architectural photography, ultra photorealistic, 8K
