Aurelia Habitat is a speculative architectural project inspired by the collective behavior of jellyfish (Aurelia aurita) and the regenerative principles of marine ecosystems. It envisions a floating modular housing system where each capsule-like unit autonomously generates energy through seawater electrolysis, connects via magnetic levitation bridges, and reconfigures itself based on spatial or environmental needs. The design integrates organically curved forms with responsive technologies—such as bio-sensor glass, dynamic lighting systems, and ocean-temperature-reactive elements—to mirror the rhythmic flow of the ocean. Key interior spaces include a panoramic lounge with an integrated pool, a dining room illuminated by fiber-optic chandeliers, a wave-simulated bathroom, and a circadian-lighting bedroom. Rather than a luxury home, Aurelia Habitat imagines an adaptive, self-sufficient living organism shaped by the logic of nature.
