A growing number of American homeowners are choosing modular home additions pre-built sections constructed off-site and installed onto existing houses. Renovators say the approach can shorten timelines and reduce neighborhood disruption.
Factory-built rooms are assembled indoors, protected from weather delays. Once transported to the property, cranes place the finished structure onto prepared foundations. Installers then connect utilities and blend exterior finishes with the original home.
Typical modular renovations include new bedrooms, expanded kitchens, sunrooms, and accessory dwelling units (ADUs). Families appreciate that much of the work happens away from the home, reducing dust, noise, and weeks of on-site construction.
Costs vary depending on location and customization, but modular additions can be more predictable because factories control material waste and labor scheduling.
Industry experts note that building codes are evolving to better accommodate modular construction, and more states are offering guidelines to streamline approvals.
With demand for faster, less intrusive renovations growing, modular options are becoming a serious alternative in U.S. remodeling projects.
