There are many variables to consider when building your home. First things first, you have to acquire the land on which you wish to build. Just like when buying a home, you should think location, location, location. Whether the lot of land is fully serviced by utilities should also be a major consideration. The lot on which you plan to build your home will also have certain restrictions which you must observe, eg. how many feet away from the boundaries you should build.
Have an architect design your building according to your specifications, and ensure that your building plan is submitted for approval to the necessary governing bodies, usually the parish council or the KSAC. Building your own home can be challenging, but can also be one of the most satisfying things you accomplish once it is over, as you should have gotten exactly what you want.
