 ; The Canberra Electoral role for 1929 lists ‘Plottel, Joseph architect 31 Queen St, Melbourne’ by dint of his having purchased property in the territory.In the late 1920s, like many architects, he undertook an overseas tour in 1929 to study the latest trends in both Europe and the United States, where he was impressed by the Spanish style houses of Pasadena and Beverly Hills.Further commissions then came in a series of factories, shops and commercial buildings in Melbourne and the inner suburbs, including Brash's at 108 Elizabeth Street in the late 1920s, while two Footscray factories for Maize Products in 1933 and Bradmills in 1934 cemented his reputation in that suburb.
