Giant Washbasin: A Shared Washing Area with a White Continuous Surface

Design a public toilet in the manner of Sou Fujimoto, where the entire building is conceived as an oversized communal washbasin. Show a long low structure in seamless white, its form a single sinuous curved surface that rises from the ground, folds over to become the roof, and dips down at the front to form a continuous shallow washing trough running the full length of the facade. Detail the trough with a row of taps at three different heights along its length — high for adults, mid for children, low enough for a seated user — all in the same brushed finish, with the water running down the curved surface into a slot drain. Show the cubicles set behind the trough as doors cut into the same white curved mass. Detail the material as a smooth seamless composite with no visible joints, panel lines or fixings anywhere, so the whole reads as one moulded object. Keep the setting as a small urban plot with paving and a few street trees. Show clear daylight with soft shadows on the curves. Photorealistic, seamless white, sculptural, eye-level three-quarter view.
