Triplex Property Development – turn one block into three!

As Perth local councils and other state government authorities look to increase the density of homes in suburbs across the Perth metropolitan area, opportunities to subdivide blocks into triplex property developments are more likely to be possible.

A triplex development is the creation of 3 dwellings on 1 block of land. The appeal for property investors is the increased potential returns that can be realised by building 3 properties whether they are for sale or for renting.

Triplex developments can be single storey units or 2 storey town houses. The most common accommodation configurations are either 4 bedrooms with 2 bathrooms or 3 bedrooms with 2 bathrooms. These offer the best return on investment and will appeal to Perth renters and buyers alike.

It is this commitment to achieving you the best possible returns for your triplex property development that sets Vision One Projects apart from the rest. Our team of Perth property experts work one on one with you, walking you through the numbers. We take the time to analyse the potential returns via a comprehensive feasibility analysis to ensure the numbers stack up at the end of the project. 

This ongoing commitment to ensuring you get the best possible return flows through to the design process too. We spend hours with our in-house design team, looking at your unique block configuration to create a design solution that will result in a cost effective build and a final product that will achieve the best possible resale value or rental return.

At Vision One Projects we genuinely care about the success of your project. This often times results in our clients coming to us with one idea in mind, but ultimately building something different. While you might think a triplex property development is perfect for your block, after running the numbers with us you might find it is better to build two larger townhouses, or conversely 4 smaller single storey units to get the best possible financial result.

When you're looking for the best deal for your construction process, you need to think about more than just pricing. It's important to ensure that you know exactly what you can build in your chosen area, according to the restrictions of local residential planning codes. 

Because we know you have a lot to think about when it comes to organising your project, we help you to understand the complex parts of project management, with a full insight into zoning regulations for your property development.

In the table below, you can see everything you need to know about your triplex project!

We are a design and construct builder and can provide a complete in-house design solution for your triplex development.

A triplex subdivision does bring with it some design and development constraints. Consideration must be given to setbacks, streetscape, car parking and vehicle access to name just a few.

Vision One Projects are your local, Perth-based solution for design and construction. We offer a comprehensive service that helps you to make the most out of your triplex development, with everything from zoning guidance, to design help. 

Since we know that designing a successful triplex subdivision can be difficult, we'll help you to address any potential issues upfront, so you can avoid costly problems further down the track.

With the support of our expert teams, you can make sure that your initial plans are drawn up with care and expertise, addressing important elements like local shire requirements and R-Codes. We'll even provide preliminary design guidance which helps you to understand the layout of your complete house area, site coverage, and your plot ratios.

There's more to a successful building project than a great price - but that doesn't mean you don't have a strict budget to stick to. At Vision One Projects, we help you to make the most out of your available funds, by giving you a completely clear and transparent quote from day one.

With our fixed price quotations, you can rest assured that you'll know exactly what you're paying for your triplex development, with a letter that outlines itemised costs for everything from preliminary site development, to finishing costs.
