The Sanitarium Health Food Company, owned by the Seventh-Day Adventists, had built an earlier factory on the banks of the Yarra River in Warburton next to their Signs Publishing complex but it was damaged by flood in 1934 so architect Edward F Billson was commissioned to design a new factory on higher ground. It was completed in 1939 and won Billson the Street Architecture Medal from the Royal Victoria Institute of Architects (RVIA) in 1940.The factory closed in 1997 but hopefully a new lease of life as a conference and reception centre awaits this handsome building with plans for refurbishment in the pipeline since around 2006.
The Warburton Adventists website includes an extensive photo gallery of their former factory.Reference:
