OMA‘s exhibition (IM)PURE, (IN)FORMAL, (UN)BUILT opened today at the École des Beaux-Arts in Paris. Made in collaboration with students at the Paris Malaquais School of Architecture, the exhibition focuses on three French libraries designed by OMA, two of them unrealized but crucially important in the development of the typology of libraries, and one about to go under construction. The featured libraries, explored in a range of archival and new materials, are the Très Grande Bibliothèque in Paris (1989), with its “strategy of the void”; Jussieu (1992), with its continuous, ramped floors; and the Bibliothèque Multimédia à Vocation Régionale in Caen, scheduled for groundbreaking in 2012. (IM)PURE, (IN)FORMAL, (UN)BUILT opens today in the Amphithéâtre d’Honneur at the École des Beaux-Arts, with a discussion between OMA Associate-in-charge Clément Blanchet and co-curators Nasrine Seraji and Thierry Mandoul from the Paris Malaquais School of Architecture. The exhibition runs until 22 July.
