Under Vernon's directorship the Arts and Craft style came to be used increasingly for public buildings. Notable examples include the Fire Stations at Darlinghurst and Pyrmont, as well as Post Offices and country Courthouses. Using the Arts and Crafts style meant these buildings were less monumental than those built by Barnet. However, Vernon also built a number of major public buildings, such as the Mitchell wing at the State Library, the Art Gallery of New South Wales, Fisher Library at the University of Sydney and Central railway station, Sydney. These buildings maintained the classical tradition. Vernon also added to a number of the buildings designed by his predecessors including Customs House, the GPO and the Chief Secretaries building.
