Duplex plans

A duplex is a multi-family home that contains two separate living units built as a single structure.
With one of the most extensive collections of affordable duplex house plans on the internet, we offer many different options, sizes and layouts. Also, we can modify our plans to meet your specific needs. There is no additional charge for most modifications. Please feel free to submit your change request via email.

Some of our duplexes have versions with more units. See apartment plans.
