Duplex homes are our passion.

dual occupancy builders sutherland shire


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

DA CDC builders sutherland shire


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 is available in your area. The Sutherland Shire Council has introduced CDC Dual Occupancy as of July 1st, 2020.

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. Opting for a CDC may also result in an increase in Floor Space Ratio (FRS) and a decrease in landscaped areas, compared with a DA. This is because the DA is controlled by the council’s own Local Environment Plan (LEP), which may differ from the controls of a CDC which is determined by the NSW Housing Code.

The Sutherland Shire Council CDC Dual Occupancy applies to R2 Zones with 600sqm minimum block size. Discover more about your property controls on the SSC LEP map.
