What Is a Duplex Home?

A duplex is a residential building divided into two separate dwellings, typically side-by-side or one above the other, sharing a common wall. Each unit has its own entrance, kitchen, bathroom, and living areas, making them ideal for:

  • Multi-generational families who want close but independent living
  • Investors looking for dual rental income
  • Homeowners wanting to live in one and sell or lease the other
  • Downsizers who want flexibility and income from their property

Two dwellings on one block mean you can double your rental yield or property value with the right design and strategy. Great for extended families, downsizers, or investors looking for options and adaptability. Modern duplexes are designed with easy-care materials and layouts that reduce upkeep and costs. Maximise your return on land that may otherwise be underutilised.
