with a dominant central tall belvedere tower. The three-storey principal block contains the state rooms for official entertaining, a secondary two-storey wing to the north contains the private apartments of the vice-regal family. The façade of the principal block features columned and pedimented windows indicating the piano nobile, a defining feature of the Italianate style. The two storey ballroom block stretches south of the main block and the tower, and is entered through a large arcaded and columned porte-cochere. The ballroom is said to have been the largest in the British Empire. The interior of Government House is elaborately decorated in contrast to the chaste lines of the exterior. In Sydney Wardell arrived in Sydney in 1878. He designed many buildings, the most notable being St Mary's Cathedral and St John's College at The University of Sydney. St Mary's Cathedral St Mary's Cathedral is slightly larger than St Patrick's Cathedral, and is the largest ecclesiastical building in Australia. Wardell designed the cathedral in the Gothic style. Work began in 1868 while Wardell was still based in Melbourne. Work continued throughout Wardell's lifetime, the cathedral finally being completed in 1928. In 2000 the spires Wardell had intended, a scheme abandoned due to lack of finance, were finally constructed. St John's College In February 1859 Wardell was appointed architect for St John's College. Working from Melbourne, he drew up the general plans and sent them to Sydney in May 1859. Wardell designed St John's College as a three-storeyed sandstone Gothic Revival building on an H-shaped plan but because of budget restrictions with a limit of A£30,000, July and August saw discussion of Wardell's design and of how much could be built within the budget. In September and October the general plans were approved by the St John's Council and the University Senate. During the period from October 1859 to April 1860 relations between Wardell and the Council deteriorated for various reasons, ultimately ending with Wardell's resignation in June 1860. Other buildings The ASN Co building is a large warehouse at 1-5 Hickson Road, The Rocks, Sydney. Designed by Wardell in the Pre-Federation Anglo Dutch style for the Australasian Steam Navigation Company and completed in 1885, it had distinctive Flemish gables and a bell tower, which has ensured it has "long been regarded as a significant Sydney landmark". Wardell also designed the New South Wales Club House building at 31 Bligh Street in
