Contractors and developers use digital twins to create interactive, three-dimensional models of homes that allow buyers to virtually tour spaces and customize options like materials, finishes, and hardware in real time. This technology provides instant cost deltas for choices such as walnut versus oak cabinets or matte-black versus satin-brass fixtures. It shortens buyer decision cycles, reduces post-contract changes, and enhances transparency, resulting in higher satisfaction and faster sales in pre-sale and new construction markets.
