This anthology radically resituates architecture as a support system in the service of infrastructure. A collection of 12 critical essays and creative projects explore the interaction between architectural spaces and infrastructural systems with the aim of responding to contemporary environmental, social, and political crises. In addition, the book presents a selection of 10 speculative design experiments undertaken in Critical Studies in Architecture at KTH Stockholm and within Design, Philosophy and Architecture at the University of Melbourne. With its integrative approach to pedagogy, practice, and theory the book contributes to an understanding of the vulnerability of planetary life and the importance of fostering relations of care in architecture.
