内外反転：構造と設備を外部へ

Design architecture where structural systems, circulation, and building services are intentionally relocated to the exterior, maximizing flexible interior space while expressing engineering as architecture in the style of Renzo Piano. Ducts, escalator tubes and steel trusses mounted entirely outside the enclosure and colour-coded by function, completely open column-free floors visible behind glass, the facade reading as a working machine, historic city context, clear daylight, eye-level composition, 24mm lens, ultra photorealistic, 8K
