TiO₂ is a research and experimental facility completed in 2004, designed by architect Masao Koizumi of C+A. Located within the Tokyo University of Science campus in Noda City, Chiba, this building showcases contemporary architectural design principles applied to scientific research infrastructure. The structure reflects a thoughtful integration of form and function, creating an environment conducive to advanced laboratory work and experimentation. TiO₂ represents an interesting example of how modern architecture can serve institutional research needs while maintaining aesthetic and structural integrity on a university campus.
