This study aims to investigate the necessity of integrating the vernacular architectural patterns of Gilan province into contemporary hotel design, in order to bridge the gap between modern tourism requirements and the cultural authenticity of the region. In recent decades, insufficient attention to climatic and cultural contexts in the design of many hospitality facilities in northern Iran has resulted in a decline in their spatial and visual quality. Using a descriptive–analytical research approach, the study first identifies key patterns of Gilan’s vernacular architecture and then examines the importance of applying these patterns in contemporary hotel design. The findings reveal that incorporating elements such as the Telar (semi-open veranda), spatial permeability, and pitched roof systems not only contributes to climatic sustainability but also enhances the experiential quality of spaces for tourists. Ultimately, the study highlights the role of vernacular architectural principles in restoring architectural identity and strengthening the relationship between buildings, users, and the natural environment within hospitality contexts.
