When the sea inundates the land,leaving no space for people to live on solid ground, the ocean will become our only refuge. The "Floating Realm" exists precisely for this moment.Its underwater design addresses the issue of limited space above sea level, utilizing ocean currents to generate electricity through the movement of tentacles,thereby meeting energy demands and promoting regeneration and environmental sustainability. The building’s design, which harmonizes with the ecosystem, allows it to integrate seamlessly into the ocean.We aspire to expand its scale, transform to an oceanic city.
