PLUTO is a conceptual nightlife environment designed as a modular architectural installation within the penthouse of the Onyx Tower in Los Angeles. The project explores how architecture can transform throughout the night, shifting between lounge, performance, and gathering space through adaptable spatial elements. Reflective surfaces, sculptural furniture, and controlled lighting conditions create an immersive atmosphere where movement, sound, and light become central components of the experience. Rather than functioning as a static interior, the penthouse operates as a spatial system that can be continuously reconfigured to support different events and performances. The project investigates nightlife architecture as an evolving environment—one that merges entertainment, architecture, and narrative into a single spatial experience.
