层层悬挑的石量体：向上放大的纪念性

Design a presidential library in the manner of Gordon Bunshaft's LBJ Library — a travertine block that grows wider as it rises, its two solid end walls curving outward and the whole crowned by a deep cantilevered top floor, with no window on the main elevations. Compose sheer cream travertine walls flaring gently outward toward the top, a heavy projecting upper storey, a broad flight of steps to a raised podium, an unbroken blank facade with a single recessed entrance, mown lawn and live oaks, hard Texas sun, low frontal view, 24mm lens, architectural photography, ultra photorealistic, 8K
