The 17th International Architecture Exhibition, in Venice from 22 May to 21 November 2021, is titled How will we live together?. As curator Hashim Sarkis explains, "the theme of the Biennale Architettura 2021 is its title": organized into five different scales, the Exhibition presents the Participants who will compete for the Golden Lion and also includes a series of research stations developed by researchers from universities around the world. Volume I of the Catalogue is dedicated to the International Exhibition, curated by Hashim Sarkis, and begins with an essay setting out the themes of the show and presenting its protagonists. Architects and studios therefore illustrate their projects with images and texts. Volume II of the Catalogue presents the National Participations, a Special Project in collaboration with Victoria and Albert Museum and the Collateral Events of the 17th International Architecture Exhibition; lavishly illustrated, it includes texts that explore the various projects on display. The graphic design of the Biennale Architettura 2021 coordinated image and the layout of the volumes are by Omnivore, Inc. Hashim Sarkis is an architect, educator, and scholar. He is principal of Hashim Sarkis Studios (HSS), established in 1998 with offices in Boston and Beirut. He is also the Dean of the School of Architecture and Planning at the Massachusetts Institute of Technology (MIT) since 2015.
