This research delves into the intricate implications of 19th-century colonial facade characteristics on residence design in Tianjin, China. As a prominent city in the early 20th century, Tianjin boasted a unique blend of foreign concessions and indigenous Chinese architectural heritage. The study aims to bridge the knowledge gap regarding the significance of colonial heritage in residence design and its cultural preservation. The research objectives encompass exploring colonial facade traits of the 19th-20th century, experimenting with their integration in modern residence design, and proposing their relevance for Tianjin's context. Tianjin's historical evolution, initially marked by its status as a treaty port shared by various nations, shaped its architectural identity. The research employs a qualitative approach, involving on-site visits and photography to gather primary data from heritage buildings, both colonial-owned and those influenced by colonial aesthetics. This method facilitates a comprehensive assessment of architectural details, enabling a deep understanding of the interplay between colonial and indigenous elements. The study also employs a survey questionnaire to further investigate how colonial facade characteristics impact the residents' perceptions, motivations, and design choices. This approach enhances the analysis of intricate design decisions that link past colonial influences to contemporary residence design. Through content analysis and data triangulation, the study reveals insights into the interwoven cultural, historical, and aesthetic factors that have shaped Tianjin's architectural landscape. By bridging the gaps in understanding regarding the effects of colonial aesthetics on residence design, this research contributes to a broader discourse on architectural preservation and urban development. It underscores the importance of acknowledging and integrating colonial heritage to create a distinctive architectural narrative that captures the essence of Tianjin's rich history. Ultimately, this study enriches the discourse surrounding architectural preservation, cultural continuity, and the symbiotic relationship between past and present in urban design.
