Slate Volume Embedded in the Hillside: Exterior of a Hot Spring Bathhouse

Design a thermal bath exterior in the manner of Peter Zumthor's Therme Vals — the building set into an alpine hillside so only a grass roof and one stone flank are visible, that flank built from sixty thousand thin slabs of local quartzite laid in layers of three differing heights to give the wall a geological grain. Compose a long horizontal wall of finely stratified grey-green stone emerging from a steep meadow, a turfed roof continuing the slope with rectangular openings cut into it, an outdoor pool steaming at one end, alpine village roofs below, cool mountain light raking the stone courses, eye-level three-quarter view, 28mm lens, architectural photography, ultra photorealistic, 8K
