Duplex House Plans

For a list of trusted home plan firms specializing in Duplex home designs, please visit the Duplex Home Plans Directory.

Duplex houses pertain to a building on one lot that can house two or more residences in one. Duplex residences can house two families on one lot, which is why they are sometimes refered to as a multi-family house. Duplex homes are becoming popular in an economic age of living in North America, and many more firms are starting to carry plans of this type in their portfolio.
