Entangled within the Earth’s five natural spheres—the lithosphere, hydrosphere, biosphere, cryosphere, and atmosphere—is a sixth: the technosphere. A term used by geologist Peter K. Haff, the technosphere is the material, spatial, and technological expression of human production. It includes feedlots and sewer systems, factories and housing, seaports and data centers, highways and croplands. Although critical to our material survival, the exponential growth of the technosphere is actively destabilizing the five spheres upon which its existence depends. The Sixth Sphere exhibition explores not only how the built environment operates at a planetary scale, but also how design can participate in systems of interdependence, reciprocity, and transition. In response to the environmental and social injustices caused by climate change, this exhibition explores how design thinking can expand beyond traditional spatial and temporal scales to approach the terrestrial in scope and complexity. To this end, The Sixth Sphere explores transcalar forms of design thinking, leveraging the cumulative power of the technosphere to imagine more viable planetary futures.

Brittany Utting is an assistant professor of architecture at Rice University and cofounder of the research and design collaborative HOME-OFFICE. Her work examines the relationship between architecture, collective life, and environmental care. She is the editor of the book Architectures of Care: From the Intimate to the Common (Routledge, 2023), and guest editor of Log 60: The Sixth Sphere (Winter/Spring 2024) with Albert Pope. Utting has been a MacDowell Fellow and a Willard A. Oberdick Fellow at the University of Michigan’s Taubman College of Architecture and Urban Planning. She holds an MArch from Yale University and a bachelor's of science in architecture from the Georgia Institute of Technology. Utting is a registered architect in New York, and prior to cofounding HOME-OFFICE, she practiced at Thomas Phifer and Partners as project designer for the Museum of Modern Art in Warsaw.
