A complement to the Biennale Architettura 2021 catalog, Expansions gathers over 80 responses to the question: how will we live together? It acts as an extension to the various themes presented by participants in the exhibition. Assembling the voices and views of different agents from the architecture field more – from academics to curators, journalists, students and more-this volume includes a collection of short essays that reveal recurring themes that are currently of interest to different architecture and design communities around the world. These include multispecies worlding, social and economic justice, the history of 20th-century modern spatial practices, environmental concerns and public modes of transportation, as well as examinations and contestations of the digital/analog binary, among others. This volume appeals to a wide range of people beyond architecture and art communities, encompassing anyone interested in the role of creative practice and expression in collectively answering the complex challenges posed by today’s unstable world.
