双生塔楼的对称构图：阶梯冠部与中央广场

Design a corporate tower in the manner of Cesar Pelli clad in pale limestone with a shaft that steps inward four times toward the top, each setback marked by a projecting horizontal band and the crown finished in a lantern of illuminated glass. Compose the stepped silhouette against a cold clear sky, narrow vertical window strips running the full height, a plain granite plaza with no planting, bare winter trees, low crisp northern light, low frontal view, 24mm lens, architectural photography, ultra photorealistic, 8K
