都会美术馆：雕塑庭园、屋顶平台与地下展厅

Design a metropolitan museum inspired by Arata Isozaki. Combine exhibition halls, outdoor sculpture gardens, educational facilities, event plazas, rooftop terraces, and underground galleries into a civic landmark emphasizing contextual architecture, layered public space, restrained monumentality, and urban connectivity. A low stone-clad volume with a walkable roof terrace reached by an external stair, an enclosed sculpture garden of gravel and clipped hedges beside it, a glazed slot revealing underground galleries below the garden, an event plaza continuing to the street, clear low sun modelling the stone, elevated three-quarter view, 28mm lens, architectural photography, ultra photorealistic, 8K
