Sendai Mediatheque is a multi-purpose cultural centre made with steel tubular lattice structures. The building glows artifically from within and contains a library, art gallery, audio-visual library, film studio, and cafe. Through a series of extraordinary technical advances - floors supported by a system of occupiable hollow tubes and sophisticated information and media networks - the building creates an environment in which people can engage in cultural activities both internally, within the structure, and externally, through digital connections to the world at large. The centre also expresses Ito's obsession with lightness and his desire to strip away anything that reminds us of gravity. The building was completed in 2001.
