A true modular home can be built from existing plans or from custom plans generated by an architect. Modular home producer’s uses computer generated plans to meet all national, state, and local building standards.
Framing for a modular home is the same as a traditional home except that true modular homes use 20 to 30 percent more material to guarantee a safe trip to the site. Basically a true modular home is over engineered to withstand the transportation process. This is also true for on-frame modular homes and to a lesser degree HUD-code homes. True modular homes are built in a climate-controlled environment using the same high quality materials used in traditionally built homes.
Construction of a true modular home follows the same path as traditionally built homes. The floor is built first, with great care taken to build a strong foundation, since this is what will carry the weight of the rest of the structure. Next, the walls are added with sheet rock already in place. Electrical, plumbing, wiring, and insulation are next.
After this, the exterior, roofing, and siding are put in place. And finally, windows, doors, bath and kitchen fixtures, cabinets, and others are added. Once the construction is complete, the structure is wrapped and shipped to the building site to be put together by a local contractor.
