イタリアンミニマリズムロビー：ピュアなボリュームと低彩度

Design a hotel lobby in the manner of Piero Lissoni, calm Italian minimalism with an almost graphic clarity. Compose the space from clean rectangular volumes: a long low reception counter as a single floating slab, a full-height storage plane with no visible openings, and a freestanding partition in a matte lacquer. Keep the palette to greys and off-whites with one single accent — a deep petrol blue or a warm terracotta — used on exactly one element. Furnish with low modular sofas in a flat-weave grey fabric, arranged in strict rectilinear groups, and slim side tables in matte metal. Keep the floor in a large-format pale grey stone with fine joints, the ceiling flat with a continuous recessed light slot following the room's perimeter. Add one large abstract artwork in muted tones and nothing else. Allow no plants, no decorative objects, no curtains — only a sheer blind. Show soft even daylight with gentle shadows. Photorealistic, calm, graphic and rigorously restrained, eye-level wide view.
