Duplex plans

A duplex is a multi-family home that contains two separate living units built as a single structure. 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 one of the most extensive collections of affordable duplex house plans on the internet, you are sure to find a floor plan that suits your project.
