A duplex house plan is as a multi-family home that is built as a single dwelling with two separate units. The two units are built either side by side separated by a firewall or they may be stacked.

If you are building in high-density areas such as busy cities or on more expensive waterfront property, this type of home can be a great investment option for the future. Probably the most typical use is if you want to provide a safe, attached living space for an elderly parent or in-law?
