Our Story



Kennett was established in Adelaide by brothers Clifford and Charles Kennett, who formed a strong partnership as stonemasons and home builders.


As Kennett’s reputation for building quality grew, so did the business. Within six years the brothers were overseeing a team of 80 tradesmen building homes in the inner-city.


The post-World War II migration boom fuelled demand for more housing, which Kennett continued to provide whilst undertaking its first commercial construction project. A hardware supplies business and joinery workshop soon followed to support increased construction activity.

1960 to 1970

Charles’s sons Neil and Dean Kennett, the second-generation, expanded the business into Mount Gambier where the company won a contract to build 50 homes for the-then South Australian Housing Trust.


Neil’s son, John Kennett, became the sole owner of the business having begun his career at Kennett as an apprentice carpenter in 1974. He steered the company to commercial construction, carving out a solid reputation and delivering many of South Australia’s major buildings.


Fourth-generation sons, James and Scott, both qualified builders with over 20 years’ experience, took ownership of the company from John, leading the company from strength to strength.


Today, Kennett operates offices in Adelaide, Mount Gambier and Melbourne with an established presence as commercial construction specialists, delivering projects across recreation and sport, aged care and health, education, retail and automotive and most recently, the multi-level residential sector.
