Basalt Architects has used marine-grade concrete to build Guðlaug Baths, a geothermal pool on Langisandur Beach in Iceland.
The baths consist of a three-tiered structure, with a viewing deck on the top, a warm geothermal pool in the middle, and a cooler pool at the bottom.
These three oval-shaped forms are each oriented differently, creating an irregularly shaped volume that nestles in amongst the large boulders of the sea wall. A staircase wraps the exterior, connecting all three levels.
Open and free to the public, the baths are designed as a recreation spot for both locals and tourists.
