The relationship between architecture and interior design is often marked by unclear boundaries and limited collaboration. Though both fields shape the built environment, differences in education, focus, and terminology create disconnects. Many architects assume responsibility for interiors, overlooking the specialized skills interior designers offer. Combined with curriculum gaps in architectural education, this limits students’ exposure to essential interior design principles. As design increasingly requires multidisciplinary input, architecture students must develop a solid understanding of interior design. This study assesses architecture students’ awareness of interior design, identifies educational gaps, and highlights opportunities to enrich architectural training. Using a mixed-methods approach questionnaires, and curriculum case studies 175 students were selected through stratified random sampling from a population of 210 across four academic levels. Findings revealed a male-dominated field, mostly aged 15–23. Students showed strong proficiency in colour theory and material selection but had notable gaps in lighting design and space planning. ANOVA results confirmed that understanding of interior design improves with academic level, with 500-level students demonstrating the highest proficiency. Survey data showed that 91.1% agreed interior design enhances architectural quality, and 98.3% valued collaboration between architects and interior designers. Students recognized the interconnectedness of the fields and the benefits of interdisciplinary teamwork. The study concludes that integrating interior design education into architecture programs is essential to produce architects capable of creating functional, cohesive, and user-centered spaces. It recommends introducing interior design concepts earlier in the curriculum, enhancing workshops, integrating interdisciplinary projects, and expanding modules on material performance and furniture ergonomics to address deficiencies.
