Delving into the essence of the Sansalvador villa requires a meticulous juxtaposition of its original architectural blueprints with a newly formulated planimetry. Conceived by Josep Maria Jujol, this architectural work in Barcelona serves as a prime example to explore his conceptual framework. Its unfinished state, scarcity of planimetric archives of the construction process, and the amalgamation of modernist and organic architectural forms and styles, give this project a distinctive character, exemplifying the architect's singular way of working. This paper undertakes a comprehensive examination of its historical evolution and conceptualization through an exhaustive analysis of primary source materials alongside the realization of a new detailed photogrammetric survey of the existing construction. By overlaying the emergent planimetry, derived from precise point cloud data collected on-site, onto the original hand-drawings, this meticulous comparative analysis unveils nuanced insights into the project's fundamental principles and the evolutionary trajectory of Jujol within the context of Catalan architectural discourse.
