Not sure how to build a duplex? Investing in duplexes is easy with the help of an expert who will guide you from the initial phone call or meeting right through to a completed development project.

Over the past 5 years we have been involved in hundreds of successful property development Australia projects. We have clients right across the country, and every member of our team has invested in our projects.

?Duplex Invest has ready-to-start duplex building/development projects in NSW, VIC, QLD and SA that have all of the hard work, costs and due diligence taken care of for you upfront.
