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!

Frequently Asked Questions


What is a duplex house plan?

A duplex house plan is a design that includes two separate living units in a single structure. Duplexes come in all shapes, sizes, and layouts, although most are in the small to midsize range and have mirror image units with the same amount of square footage, bedrooms, and bathrooms.


What are the characteristics of a duplex home?

Duplexes feature two units in the same structure, meaning two residences share the same foundation, roof, and a firewall. They often have mirror image units, but there are also designs with unique floor plans that wrap around each other in a way that creates different layouts. Some duplexes can even look like a single-family house!


What are the advantages of duplex houses?

Duplexes are faster and more affordable to build than two single homes, so they're ideal for areas that need more housing and for families to would like to keep close and save money. Some buyers also build for themselves and rent out the other unit to help offset the mortgage. If you want a budget-friendly investment, a duplex could be exactly what you're looking for.
