Prefabs, short for prefabricated buildings, are structures made from pre-manufactured components that are assembled on-site. These components can include walls, floors, and roofs, which are produced in a factory and then transported to the construction location. This method can significantly reduce construction time and costs compared to traditional building methods. The use of prefabs has gained popularity in various sectors, including residential homes and commercial buildings. They are often designed to be energy-efficient and environmentally friendly, making them an attractive option for sustainable development. Companies like Modular Home Builders specialize in creating these innovative structures.
