In the context of widening political divides and growing economic inequalities, curator Hashim Sarkis calls on architects to imagine spaces in which we can generously live together. The architects invited to participate in the Biennale Architettura 2021 are encouraged to include other professions and constituencies—artists, builders, and craftspeople, but also politicians, journalists, social scientists, and everyday citizens. In effect, the Biennale 2021 asserts the vital role of the architect as both cordial convener and custodian of the spatial contract. In parallel, the 17th Exhibition also maintains that it is in its material, spatial, and cultural specificity that architecture inspires the ways we live together. The Biennale Architettura 2021 is motivated by new kinds of problems that the world is putting in front of architecture, but it is also inspired by the emerging activism of young architects and the radical revisions being proposed by the profession of architecture to take on these challenges. But more than ever, architects are called upon to propose alternatives.
