Our Histoy

BGi Building Group is a family-owned, Barossa based building company, Specialising in Steel Construction. Since its establishment in 1977 by the Zerna Family, BGi has established itself as a trusted and reliable company within the building and construction industry. Purchased by family in 2021, Charles & Meggie Edwards continue to see BGI Building Group a South Australian Family owned & run business.

BGI Building Group formally established as Barossa Garages in 1977. The business started installing residential sheds, verandahs and fencing in and around the Barossa region. In 1987 Frank Zerna purchased the Nuriootpa property, and began building its own premises where it continues to do business to this day. Upon completion the business soon began fabricating and manufacturing its own steel framed structures. 

Paul Brown joined the business in 2000 and his experience as a qualified engineer was influential in seeing the business move into the commercial & industrial sector. Working on larger winery, & industrial buildings has now complimented the business services as it continues to offer clients a wide range of building services from domestic to commercial.
