Thin Slab Eaves Entrance: Cantilevered Rain Canopy and Glazed Vestibule

Design a museum entrance in the manner of Yoshio Taniguchi where an impossibly thin steel canopy cantilevers eight metres over the approach with no columns, its edge tapering to a knife line. Compose the canopy soffit in flawless white, frameless glass doors set back beneath it, a grey granite floor running unbroken from outside to inside, a single flush-mounted line of light in the soffit, overcast daylight against the darker recess, low frontal view under the canopy, 24mm lens, architectural photography, ultra photorealistic, 8K
