Museum of Thick Walls and Narrow Gaps: Monochromatic Volumes and Oblique Light

Design a museum gallery in the manner of Ricardo Legorreta lit only by a tall narrow slot cut the full height of a thick masonry wall, so a single blade of daylight sweeps across the coloured plaster as the day passes. Compose deep ochre walls with no cornice or skirting, a polished dark stone floor, the light slot's edge razor-sharp against the shade, a single large canvas on the far wall, dim interior with one intense bright band, eye-level view along the wall, 35mm lens, interior photography, ultra photorealistic, 8K
