傾斜階段状アトリウム：層状に張り出した客室バルコニー

Design a hotel atrium in the manner of John Portman with a triangular section: the room balconies step outward as they rise so the void widens dramatically toward the skylight, leaving a vast overhanging cliff of concrete terraces. Compose the sloping wall of stacked balconies filling the frame, hanging planters spilling down every level, a large abstract metal sphere sculpture on the lobby floor, glass lifts on the vertical face, warm lighting under a bright skylight, low view up the slope, 24mm lens, interior photography, ultra photorealistic, 8K
