外露服务核：把楼梯与管线推到建筑之外

Design a building in the manner of Richard Rogers where every service — stairs, lifts, ducts, pipework and structure — is pushed outside the envelope so the interior is left entirely free and the outside becomes a legible diagram of how the building works. Compose exposed stainless ventilation ducts, external glass lift capsules and a bolted steel exoskeleton hung on the outer face, the glazed floors behind visibly clear of obstruction, a service tower standing proud of the roofline, cool overcast light on polished metal, low three-quarter view, 24mm lens, architectural photography, ultra photorealistic, 8K
