In the middle of the nineteenth century, a utopian impulse flourished in the United States through the circulation of architectural and urban plans predicated on geometrically distinct designs. Though the majority of such plans remained unrealized, The Shape of Utopia emphasizes the enduring importance of these radical propositions and their ability to visualize alternatives to what was then a newly emerging capitalist nation.

Drawing diagrammatic plans for structures such as octagonal houses, a hexagonal anarchist city, and circular centers of equitable commerce, these various architectural utopians applied geometric forms to envision a more just and harmonious society. Highlighting the inherent political capacity of architecture, Irene Cheng showcases how these visionary planners used their blueprints as persuasive visual rhetoric that could mobilize others to share in their aspirations for a better world.

Offering an extensive and uniquely focused view of mid-nineteenth-century America’s rapidly changing cultural landscape, this book examines these utopian plans within the context of significant economic and technological transformation, encompassing movements such as phrenology, anarchism, and spiritualism. Engaging equally with architectural history, visual culture studies, and U.S. history, The Shape of Utopia documents a pivotal moment in American history when ordinary people ardently believed in the potential to reshape society.
