Three Mushrooms: Cylindrical Volume and Cantilevered Dome

Design a public toilet in the manner of Toyo Ito, formed as three separate mushroom-like volumes. Show three cylindrical blocks of differing diameters standing close together but not touching, each topped with a dome-shaped roof that overhangs the cylinder well beyond its wall so the profile reads unmistakably as a mushroom cap on a stem. Detail the roofs as smooth continuous curves in a pale off-white, their undersides equally smooth with no visible structure, and the cylinders in the same pale finish so the whole group reads as one family. Show the gaps between the three volumes as the circulation, sheltered by the overlapping caps. Detail each cylinder with a single curved door and a slim vertical slot of glazing. Set the group at the foot of a flight of stone steps rising into a wooded shrine precinct, with tall trees behind and dappled shade falling across the caps. Show the ground in compacted gravel with a stone edge. Include a person entering. Photorealistic, soft and organic, pale white against deep green, low eye-level view.
