Author of fragile, evanescent, powerfully poetic buildings, Junya Ishigami has won the BSI Swiss Architectural Award, bestowed by the Accademia di architettura di Mendrisio in collaboration with the Archivio del Moderno of the same city, with an endowment of 100,000 Swiss francs. This is the fifth cycle of a prize for architects under 50 which set its bent for socially committed architecture by acknowledging Solano Benítez (2008) and Diébédo Francis Kéré (2010), continued supporting ‘peripheral’ cultures by acclaiming Studio Mumbai’s Bijoi Jain (2012), hailed the rigor and maturity of José María Sánchez García (2014), and now honors the unique world, at the threshold of art, of Junya Ishigami.
