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.

This can include property sold to see an immediate development profit, or a lease property to secure a positive cash flow.


Over the past 5 years we have been involved in hundreds of successful property development 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 across Australia that have all of the hard work, costs and due diligence taken care of for you upfront.

For comprehensive property development Australia wide, we project manage to completion, sale, or rental.

Alternatively, if you want to undertake your own specific duplex or development project, need help finishing one or require help keeping your costs of build a duplex under control, we can advise you about our fully inclusive project management services.
