Why Do People Build Duplexes?

As Investments

The most common reason duplexes (and townhouses) are built are for investments(*2). A couple wanting to pay off their mortgage faster may opt to invest in a duplex to generate income. Rather than building one house on a block, duplexes provide investors with two rental incomes. Students, young professionals, and small families wanting a more affordable rental option often look to duplexes. In built-up neighbourhoods, duplexes double the number of people who can live close to amenities, work, and schools(*3).

Duplex, Townhouse, Granny Flat and Dual Occupancy House Builders

During your research on duplexes, you are likely going to stumble upon townhouses, granny flats and dual occupancies. All of these housing types are similar but there are key points of difference between them.


Duplexes are two separate homes built on the same block – under the same roof. They are completely separate homes that only share one central dividing wall(*1).


The key difference between a duplex and a townhouse is height. Townhouses usually have multiple storeys. You may also be able to fit more than two townhouses on a block.

Granny Flats:

Granny flats are similar to duplexes; however they can be stand-alone dwellings. The flat may be built at the back of the property or attached to the main house.

Dual Occupancies:

Dual occupancies share a main central wall which includes a lockable door connecting the two homes. The door (as opposed to the wall in a duplex) makes it easy for the home to be integrated back together later should the need arise. This is often a popular choice for families caring for older family members who are still wanting to maintain their independence.
