Duplex homes are our passion.


A duplex is a savvy approach to building. As a result, they are becoming increasingly popular for home builders and home buyers alike. Many modern developments are innovative, spacious and elegant. High-end design and luxury finishes have recently become a standard expectation in new duplex homes, particularly in the Sutherland Shire region.

Building a duplex can have the potential to deliver strong investment returns and, therefore, is an attractive option for property owners looking to optimise their financial position. People choose to build a Dual Occupancy home for a variety of reasons;

  • Downsizing for retirement
  • Upsizing for young families
  • Family members working together to create housing solutions
  • Investment or profitable opportunities
  • Housing affordability and reduced mortgage pressure

The NSW State Government has changed its building code to allow for Complying Development Dual Occupancy housing. Each individual council will make their own decision as to when and how they implement the code. View your local council’s website to determine if Complying Development (CDC) Duplex approval and construction is available in your area.

A complying development significantly speeds up the building process. Providing the design meets the requirements of the relevant building code, CDC approval is fast-tracked with a building certifier.
