Design a religious building using exposed concrete, pure geometry, minimal openings, controlled natural light, and profound spatial silence to evoke spiritual contemplation inspired by Tadao Ando. A windowless concrete box approached along a blank wall, one narrow horizontal slot at floor level admitting reflected light, absolute stillness, no decoration or furniture beyond simple benches, dim interior with one bright band, eye-level composition, 35mm lens, ultra photorealistic, 8K
