One way to afford the cost of building a new home is to include some rental income in your planning with a duplex house plan. This income from one or both units may even cover the total mortgage payment! At least you will have cash flow that you can count on. Our duplex floor plans are laid out in numerous different ways. Many have two mirror-image home plans side-by-side, perhaps with one side set forward slightly for visual interest. When the two plans differ, we display the square footage of the smaller unit. Garages may be attached for convenience, or detached and set back, keeping clutter out of view.
