Invisible is a book on St. Louis design practice, Axi:Ome led by Heather Woofter and Sung Ho Kim. A collection of essays, built, unbuilt and conceptual projects which maps the trajectory of the last seven years of work from 2015 through 2022. The book covers 24 projects in different cultures and landscapes around the world with various programs and scales. Nader Tehrani, Eric Mumford, Alan Balfour, Jennifer Yoos, Nanako Umemoto, and Jessie Reiser provide insightful texts supporting and articulating critical frameworks of Axi:Ome, while defining a discourse of complexities in contemporary practice that is emerging from academic expectations. The book documents the invisible ethos that constructs a project in an intricate world that challenges practitioners to re-think and re-examine how they position into architectural spectrum. Invisible cartographs and chronicles the legitimisation of architectural practice that engages the pedagogical visions of the profession and the education.
