Perth Triplex Development FAQs
What is a triplex development?
A triplex development involves building separate, self-contained homes on a single block of land. These homes may be attached, semi-detached, or standalone, depending on the triplex design, the available land space and zoning restrictions. As a type of multi unit development, triplex developments are increasingly popular because of the many benefits associated with these property development and investment projects.
What are the benefits of triplex development?
There are many benefits to undertaking a triplex development in Perth. These include maximising property value by subdividing and building three homes on one original block, and multiple income streams by renting two or more to tenants. Another key benefit is that triplex development can deliver a flexible investment strategy over the long-term – sell all, keep all, or mix.
Is a triplex development more complex than a duplex development?
Yes – despite having just one more dwelling than a duplex, undertaking a triplex development is generally more complex than a duplex development. However, as there can often be significantly higher financial rewards for building an extra dwelling on a block, many property owners recognise the benefits. However, it’s advisable to work with a trusted triplex builder in Perth with strong property development experience.
Why should I work with a triplex developer on my project?
As there are unique challenges involved when building a triplex in Perth or anywhere in Australia, working with a triplex developer on your project offers several key benefits. These include their specific experience with the unique design, engineering, and zoning requirements for multi unit properties, specialist triplex designs for Perth’s landscape and climate, insights into project feasibility and compliance, risk mitigation and streamlining approvals.
Are triplex designs aesthetically pleasing?
Triplex designs for Perth properties can be very aesthetically pleasing – when you work with the right triplex development team. A triplex design needn’t be a duplex design plus one, and there are many options in terms of layout that can be leveraged to create a floorplan that appeals to all kinds of homebuyers, not to mention a facade that delivers amazing street appeal.
