Smart Interior Design and Decoration Using Artificial Intelligence

The rapid advancement of globalization has enhanced the demand for remote visualization and personalization of residential and commercial spaces, particularly for users who plan construction or renovation of their homes. Tra- ditional interior design practices are often expensive, time- consuming, and profoundly dependent on manual expertise, making them inaccessible to many users. Recent advance- ment in Artificial Intelligence (AI), especially diffusion- based generative models and 3D visualization technologies, have opened new avenues for intelligent, automated, and user-centric design solutions. This paper introduces a smart interior design framework that combines AI-generated de- sign ideas with cross-platform mobile tools and immersive 3D visualization. The anticipated system is working as a Flutter-based mobile application that permits users to up- load room images or floor plans. The system produces mul- tiple design possibilities using Stable Diffusion, ControlNet, and DreamBooth models, customize furniture and style, and experience designs through Unity-based 3D virtual tours. Cloud-based services utilizing Firebase which offer scalable storage and virtual teamwork. The presented solution tackles important research areas in cross-platform deployment, improving advanced visualization, and virtual design part- nership. Experimental assessment validates improved sat- isfaction, less design effort, and boosted realism, highlight- ing the potential of AI-powered design automation for real- world applications.
