白い曲線屋根とアトリウムの木：離れの公園コテージ

Design a park toilet pavilion in the manner of Fumihiko Maki, composed as a light structure rather than a block. Show a thin white roof of gentle continuous curves floating over several separated volumes, its underside smooth and its edge tapering to a fine line so the roof reads as a single hovering plane. Detail the plan as broken into distinct small volumes with gaps between them, arranged around a small open central patio where a young tree grows through an opening in the roof, so daylight and sky reach the middle of the building. Show the washing area placed at the open edge with two basins at different heights — one at standard height and one low enough for a child or a seated user — both on a continuous white counter. Detail the walls in a smooth pale render with rounded corners, and the openings as generous and unframed. Include a bench built into the outer face of one volume where people can sit and wait. Show soft daylight and a park with children playing beyond. Photorealistic, light, white with green, eye-level view.
