Duplex House Plans

A duplex house plan provides two units in one structure. No matter your architectural preferences or what you or any potential tenants need in a house, you’ll find great two-in-one options here! 

Our selection of duplex plans features designs of all sizes and layouts with a variety of features. Each duplex floor plan typically provides mirror image or very similar units, although some do provide unique units with distinct entrances to make the structure look like a single-family home. Whether you choose to rent out the second living space of your duplex or use it to cut costs within your own family, these home plans make a great choice for a budget.

Our experts are here to help you find the exact duplex house plan you're after. Reach out with any questions by email, live chat, or calling 866-214-2242 today!
