双体量高塔：高塔与低座之间的对话

Design an office complex in the manner of Eduardo Souto de Moura's Burgo Tower — a pair of deliberately unequal volumes on one plot, a slim vertical slab and a long horizontal block, both clad in the same dark granite and glass so the contrast is purely one of proportion. Compose a narrow tall tower with a rigorously regular grid of black granite piers and recessed glazing, a low broad block of identical detailing beside it, a shared paved plaza, an avenue with plane trees, cool Porto daylight, low three-quarter view showing both volumes, 24mm lens, architectural photography, ultra photorealistic, 8K
