预制山屋：高山环境中的极简住宅

Design a high-altitude refuge in the manner of Charlotte Perriand, prefabricated in the valley, flown in by helicopter and bolted onto a rock ledge, with every interior dimension driven by the minimum a body needs to sleep, cook and dry wet clothing. Compose a compact aluminium-clad shelter on a steel frame lifted clear of the rock, a single large window facing the valley, bunk berths visible through the glass, snow banked against the windward side, bare granite and cloud below, hard alpine light, low three-quarter view, 28mm lens, architectural photography, ultra photorealistic, 8K
