氷河博物館：登れるコンクリートのボリュームと展望テラス

Design a glacier museum in the manner of Sverre Fehn's Norwegian Glacier Museum — a low concrete building placed on a bare valley floor with two long straight flights of steps running up its flanks to a viewing platform on the roof, so the building is also a lookout aimed at the ice. Compose a grey board-marked concrete mass with symmetrical external stairs climbing to a flat roof terrace, a curved wing at one end, no ornament or cladding, steep barren mountains and a glacier tongue behind, cold clear northern light, low three-quarter view, 24mm lens, architectural photography, ultra photorealistic, 8K
