Thinking about adding on to your home? It may be easier than you think. It may be as simple as ordering modules from a factory which builds them to your specifications, then delivers them to your extended foundation. Less fuss, less mess, and, since the process is quick, you don't even need to move out while the work's being done. What will the modules look like? They'll look like however you want them to. Hire an architect to design your modules according to your needs as well as to mimic the architecture of your existing house. To see which modular manufacturers service your area, visit PrefabExpo.com. It will save you a tremendous amount of time searching. Just type in the Zip code of your home and you'll know instantly what's available to you in your neighborhood. Now, since modular building methods must follow the normal building code for your area, there will be no difference in quality, except that the modules will be stronger, since they will have to endure the rigors of transportation by truck and withstand the stresses of being hoisted into place by a large crane. Although modules must be short enough to go under a freeway overpass, modules can be stacked on top of each other at the building site in order to achieve multiple stories. Each module has both floor and ceiling joists, so when they are stacked, say for a 2-story home, two sets of joists separate the first and second floors, adding even more strength and fire safety to your new addition. Your modules are built in a climate controlled factory, then shipped out on trucks to your building site. Once your modules are set, a drywaller can come in and cover all the seams between the modules. Next, electricians, plumbers, and heating and air conditioning contractors come onto the scene to tie all the systems into their various utilities. The modules come pre-wired according to your instructions. In other words, you decide, beforehand, the locations of your electrical, telephone and cable outlets. Then, all that's left for your electrician to do is to connect the wires to your existing breaker box.
