Interior design practices are deeply influenced by the cultural values and traditions of the societies in which they evolve. In urban environments, where diverse cultural groups often interact, these influences can be particularly pronounced. This paper investigates the role of cultural values and traditions in shaping interior design practices in urban spaces, with a focus on how they contribute to the creation of meaningful, functional, and aesthetically resonant spaces. Drawing on case studies from cities around the world, including Dubai, Hong Kong, and Istanbul, the research explores how designers integrate both traditional cultural elements and contemporary design trends to create hybridized interiors. The study finds that cultural traditions and values significantly shape spatial organization, material choice, and aesthetic expression, and that these elements often merge with globalized design trends, resulting in unique and culturally sensitive spaces. The paper highlights the importance of cultural sensitivity in interior design practice and suggests that understanding the cultural context is crucial for creating spaces that are both functional and reflective of the identities of the people who inhabit them.
