Integration of AI, BIM, and CGI in Interior Design: From Conceptual Visualization to Managed Construction Delivery

Abstract

The convergence of artificial intelligence (AI), building information modeling (BIM), and computer-generated imagery (CGI) is redefining how interior design projects are conceived, communicated, and constructed. Despite rapid market growth, a persistent gap remains between photorealistic conceptual visualizations and the technical documentation packages that general contractors require to execute complex designs. This study analyzes how AI-generated design concepts, high-fidelity CGI renders, and BIM-based construction data can be integrated into a coherent project delivery workflow, with particular attention to the US residential and commercial interior design market. Through systematic literature review, analysis of verified market data, and a practice-based case study of a transatlantic design firm operating in the United States, the research proposes a four-phase integrated workflow model connecting client brief analysis, AI-assisted concept generation, photorealistic CGI production, BIM documentation, and contractor coordination. Key findings indicate that firms combining European design methodology with AI-augmented visualization and BIM-linked documentation achieve measurable gains in project turnaround speed and client approval rates, while operating at price points competitive with domestic providers. The results are relevant to design professionals, construction managers, and technology developers seeking to close the visualization-to-construction gap in the interior design industry.
