OCTA Hall is an installation art museum designed as an interactive field where architectural order and visitor movement shape the experience together. A regular 8x8 structural grid organizes the project and provides clarity, repetition, and scalable logic. Within this framework, layered volumes of different heights, double height voids, and movable partitions generate diverse spatial conditions, from open halls to semi open galleries and enclosed rooms, allowing multiple curatorial scenarios and temporary installations. As visitors navigate the building, their paths create a second irregular layer of order over the regular grid, turning circulation into a living diagram and making the audience an active part of the spatial narrative. Technically, the design relies on a clear structural frame, repeatable modules, and flexible planning so spaces can adapt over time without losing coherence.
