This project develops the first comprehensive study of Le Corbusier’s master plan for Buenos Aires (1938–1940), a critical yet often overlooked episode in modern urban history. The research phase involves locating, gathering, and analyzing three key sources: Le Corbusier’s 54-page manuscript prepared in Paris in 1939; the spiral-bound model produced in Buenos Aires by Jorge Ferrari Hardoy and Juan Kurchan, incorporating photographs, collages, and new design strategies; and the original sketches and drawings preserved at the Fondation Le Corbusier in Paris. By examining these materials in parallel, the project reconstructs the editorial, graphic, and conceptual transformations that shaped the plan, highlighting its fragmentary and unfinished character. This work includes archival research, critical writing, and the outline of a volume that reproduces and contextualize these documents, ultimately opening new perspectives on transnational collaborations, the politics of urban modernism, and the role of architectural archives in shaping cultural memory.
