面向广场的不规则立面：像乐谱一样的开窗

Design a town hall annex in the manner of Rafael Moneo's Murcia extension — a flat sandstone facade facing a baroque cathedral across a small square, its stone piers and openings set at irregular intervals and different depths like notes on a stave, answering the cathedral without imitating it. Compose a rectangular stone elevation with vertical members of varying width and setback, glazing recessed at differing depths behind them, no cornice or symmetry, the ornate cathedral front visible opposite across a paved square, warm Spanish evening light raking the piers, frontal eye-level view, 28mm lens, architectural photography, ultra photorealistic, 8K
