Prefab homes, which are short for prefabricated homes, are primarily ready-built in factories and delivered to the site where assembly will be done. They are sustainable and moveable housing. Traditional personal house is built on-site and pieces by pieces and days by days. Unlike that, a prefab home can be finished in fast construction since all the parts are done before being transferred to the job sites. All homeowners need to do is a simple assembly or even zero assemblies in some prefab homes, which means to move into it immediately.
