Duplex Development
What is a duplex?
A duplex is a type of subdivision. A subdivision involves creating two or more blocks of land from a single ‘master’ block. The master block may include an existing dwelling on it, which may or may not require demolition to make room for the new land titles and the future residences built on them. Duplex developments usually come in two variations:
In front & behind
This type of duplex design involves subdividing the land into two titles in order to build two dwellings, one behind the other.
Side by side
This type of duplex design involves subdividing the land into two titles in order to build two dwellings, side by side.
What is the difference between a duplex and triplex development?
A duplex is defined as two self-contained dwellings under one roof with one shared wall that can be built on a single title or multiple titles. By selling two titles, you can sell each newly created dwelling individually, making them popular investments that provide multiple rental incomes at a lower land cost when compared to detached houses. On the other hand, a triplex development involves dividing the land into three and building three separate living units.
So, the main difference is fairly simple – a duplex design has two units, while a triplex has three units. Still, it can be hard to decide which is your best option. Both have great investment benefits – the decision to build either two or three homes on your block usually comes down to zoning guidelines.

What is the difference between a duplex and triplex development?
Building a duplex on your Perth block has a number of investment benefits to both the investor and the home buyer. Some of these include:
- Higher return on investment
- Cost savings
- Reduced stamp duty
From a development perspective, the biggest advantage of building a duplex is that it gives you options that can be mixed and matched to your needs, investment goals and retirement plans. You can sell the new properties, rent out the properties, or a combination of both.
Most people who build a duplex in Perth or the South West want to turn the newly created properties into revenue streams. However, many investors develop with the intention of living in one of the units and renting out the other. One common reason for this is to accommodate parents – by developing a duplex, you can turn one property into two residences that allow you to live in close proximity with each other while still maintaining your own privacy.
