Lost beside sacred mountain Mount Tai, Jiunvfeng Bubble Pool is located on a rocky ridge above Dongximen Village in northern China. We attribute it to nature in the shape of “Crystal Shells in Cloud Sea” and make it coexist with nature as well. Thanks to the special structure to make it a pure and smooth shape. The large overhanging special-shaped curve steel keels with column-free make it possible for shells-like appearance. And the opening offers panoramic views of the surrounding mountains and forests. The external insulation layer is covered with stainless steel surface. White paints are sprayed after high-precision surface joint. The openings together with large-area transparent glass windows render the demarcation between inside/outside ambiguous. Due to the privacy demands, the changing room and gym are located next to the pool, and the shells’ openings are set in different orientations. These small volumes grow up well among the village and the mountains.
