Y-Shaped Curved Office Building: Base of Columns and Sunshade Grille

Design an international institutional headquarters in the manner of Marcel Breuer with a Y-shaped plan, its three curved wings lifted clear of the ground on heavy tapered concrete pilotis so the plaza runs continuously beneath. Compose a gently concave facade of precast concrete sun-shading frames holding recessed glazing, the pilotis flaring where they meet the slab, an open paved forecourt with a single abstract sculpture, no cars, soft late-afternoon light casting deep shadow under the building, low view up the pilotis, 24mm lens, architectural photography, ultra photorealistic, 8K
