Duplex house plans

Apartment plans with 2 units per building. These plans were produced based on high demand and offer efficient construction costs to maximize your return on investment. In most cases, we can add units to our duplex plans to achieve a larger building should you need something with more apartment units. There is no additional charge for most modifications.
Please use our contact page to submit your request via email.

With a wide variety of floor plans and layouts, you are sure to find a plan that suits your project. We can also work with you in combining units from different plans to achieve the final design you need.
