PLATFORM is the annual magazine of The University of Texas at Austin School of Architecture. It serves as a “platform” for the school to investigate the intersection of its research, practice, and pedagogical interests with a broader audience. Each issue of PLATFORM features articles of topical interest in the disciplines of architecture, architectural history, community and regional planning, historic preservation, interior design, landscape architecture, sustainable design, and urban design. This issue, titled Preservation in the Americas: Finding our shared history, edited by Associate Professor Benjamin Ibarra-Sevilla, focuses on how we define and interpret cultural heritage in the Americas and beyond, and looks at historic preservation as a live and dynamic field of investigation and professional work related to the built environment.
