Prefabricated structures use an assembly line construction process to build a low cost housing alternative that is modern, affordable, energy efficient and customizable. Types of Prefabricated Houses Modular homes are constructed in pieces that include electrical finishing, windows and the walls to be assembled on site. They are built in a couple of months, are extremely cost efficient and consist of prefabricated units or modules. The units are joined together at the site and are usually much bigger than the manufactured ones. Instead of using steel posts and steel frames for support, they use wooden beams that can be stacked and rearranged. Modular housing can also be panelized like transportable homes in QLD, which means that the homes are constructed in a factory and shipped to the site. They may also be precut homes that are designed like a jigsaw puzzle which has pieces that fit seamlessly in unique ways. Manufactured homes or mobile homes use chasses or non-removable steel that gives it permanent support. They are a low cost alternative that can be placed on permanent foundations. Construction of Prefabricated Homes Prefab granny flats in QLD follow certain construction steps from the inside out. First the floors are assembled and the wooden frame for attachment of wall panels is placed under the floor. Next, using nails and bolts the wall panels are attached and the windows are cut out before the insulated panels are attached. The electrical wiring, plumbing and ceiling are installed next and then workers assemble the roof that has been manufactured off site. Finally the interior and exterior walls are added with cabinets, backsplashes and siding. The walls are then painted before it is transported to the actual site. While most of these homes can be built and installed within a day, customizations can change or extend the time frame.
