The thesis addresses a segment of the architectural and construction work of Boren Emili within the context of the urban development of Sušak during the interwar period. Specifically, it examines the period from the 1920s to the 1930s, during which significant changes occurred in the city’s urban development influenced by global trends. The work also covers the historical context essential for understanding the circumstances in which Sušak was situated at the time, including its political and economic transition following the Treaty of Rapallo. It contextualizes the influence of modernism in architecture, particularly through the use of new materials like concrete and steel, as well as the simplicity and functionality of design. Special attention is given to Emili’s projects on Strossmayer Street: the house of Franjo Zafred, the renovation of Franjo Rudan’s house, the design and construction of a five-story building for Žiga Wortmann and Eduard Pajkurić’s children, and the design and construction of the Benko and Emili houses. These projects represent urban and architectural advancements tailored to the contemporary needs of both the clients and the city of Sušak during the interwar period. Through the lens of these projects, Emili's architectural vision is analyzed, revealing its alignment with European and national modernist trends that also left their mark on the local setting. My contribution lies in the exploration of previously under-researched works by Boren Emili, with a focus on a comprehensive approach to the projects on Strossmayer Street, where the issue of the authorship of certain buildings is thoroughly questioned. The thesis employs a methodology that includes thorough archival research, comparative analysis with previous works, and a critical evaluation of the urban and architectural context of Strossmayer Street. The work contributes to a more comprehensive insight and evaluation of Boren Emili's architectural and construction oeuvre in Sušak during the interwar period.
