This study marks the culmination of my two-year master's journey in the Architecture for Sustainability program at Politecnico di Torino, with a focus on maintaining a strong connection to my homeland, Iran. Upon arriving in Italy, I observed a pronounced dedication to historical monument preservation, contrasting sharply with Iran's challenges in this area. Inspired by Italy’s preservation methods, I aimed to integrate heritage conservation and sustainability at the Shahrestanak Palace, a 19th-century historical site in Karaj province near Tehran. The initial chapter provides a historical context, outlining the evolution of Tehran and its architectural heritage, emphasizing the significance of preserving Shahrestanak Palace.
