New homes built by hand can take several months or more to build, depending on how complicated your design is. Prefabricated homes have a much shorter construction time. Depending on where you live, it could take just 2-3 weeks for your home to be completely assembled at a factory and shipped to its final destination. So if you’re planning to build a new home, maybe it’s time to look into pre-built homes. They might be just what you need!
