Sunshading Grilles and the Geometry of Light: Shadow Patterns on White Walls

Design an elevation in the manner of Richard Meier where a deep white brise-soleil grid is used less for shading than for drawing — the sun's movement across it prints a slowly rotating geometric pattern on the white wall behind, making light the building's only ornament. Compose a projecting white louvre frame standing half a metre off a plain white wall, a precise chequer of shadow cast across the surface, a glazed slot behind partly in shade, no material other than white enamel, glass and travertine, hard midday sun with razor-edged shadows, oblique close view, 50mm lens, architectural photography, ultra photorealistic, 8K
