This course explores the complexities of Indigenous architecture in the United States, not only as a study of historical and cultural influence on the built environment but also as a reflection of Indigenous sovereignty, articulated through spatial design. The seminar delves into the principles, philosophies and socio-political settings that shape a range of Indigenous architectural practices where themes of communication and “knowledge sharing” play a fundamental role in design. From the construction of schools and museums to cosmological structures and water management facilities, the architectural function of exchanging or sharing knowledge through the built environment weaves a common narrative in Indigenous architecture. The premise of “knowledge sharing spaces” informs the critical lens in which to evaluate past and present architecture designed by and/or for Indigenous communities. Throughout the semester, case studies that both contest and contend with broad issues of colonialism, Eurocentric narratives of indigeneity, cultural appropriation, environmental stewardship, community engagement, and Indigenous recognition, are examined within the context of communicative architecture. Amplifying Indigenous voices and viewpoints in the practice of “knowledge sharing spaces” reveals new depth and layers to architectural design that is primed for informed analysis and discussion.
