Features of Duplex House Plans

A duplex is a single building divided into two separate living units, each with its own entrance and amenities. Here are some common features of duplex floor plans:

Two independent living units

Each unit is a separate home with its own entrance and living areas. 

Separate entry

Each house has its own separate entry, its own kitchen, bathroom and living space.

Common walls

Units share one or more common walls which helps save on construction costs.

Outdoor spaces

Some designs incorporate shared or individual spaces such as garages or patios.

Mirror image

Side-by-side duplexes are often mirror image units. However, there can be house designs for duplexes with unique floor plans that wrap around each other to create different layouts. 

Types of duplex house plans

One-up, One-down duplexes

Stacked duplexes or one-up, one-down duplexes comprise two dwelling units arranged on top of one another each with an entry from the street. This type of duplex has the appearance of a small-to-medium single-unit house. 

Side-by-Side duplexes

In this type of duplex building plan, units are adjacent to each other and share a common wall, providing more privacy and individual outdoor spaces.

Ranch style duplexes

Benefits of Duplex Floor Plans

Cost efficiency

The cost of building a duplex is often lower than that of a single family home. This makes the duplex an ideal choice if you are a first time homeowner or building your equity.

House hacking

Many homeowners occupy one unit and rent out the other to generate income and offset the mortgage expenses. 

Multigenerational living

Duplexes often provide close and independent  living quarters for extended family members or parents promoting togetherness while maintaining space.

Flexibility

Homeowners can always convert the duplex into a single family home when the need arises.

AirBnB Potential

If your duplex is near a vacation spot or a tourist location, you could convert one unit into an Airbnb rental. This allows you to charge premium rates and earn additional income.

Investment Potential

The property value of duplexes finds appreciation because of the rental income potential, making them a sound investment option.
