1927 Peter and Zeppa’s son, John Peter, was born on January 27 and, soon after, work began on the Bank of New South Wales building at 341 George Street, Sydney, which featured prominent sienna yellow scagliola. The 1920s also saw the opening of a  number of Sydney’s great department stores. Melocco Brothers worked with plaster, marble, mosaic and scagliola on David Jones, Farmers and Mark Foys (now the Downing Centre).
