It was hailed as the ‘arrival’ of architecture and art into Sydney – a turning point for the colony. New technologies in telegraphy and cheap postage required a city communications hub and social centre. The GPO, designed by Colonial Architect, James Barnet, was completed in stages between 1866 and 1891, when its clock tower was finally added. It would be the tallest civic structure in the city. Straddling 114 metres along Martin Place, it also remains one of the largest sandstone buildings in New South Wales.

Its golden sandstone was quarried from Pyrmont, and Barnet commissioned Italian immigrant sculptor Tomaso Sani to carve its reliefs depicting colonial life, but – a little too life-like for some – they were denigrated by critics as ‘caricatures’.

Despite its controversies, the GPO prevailed as the hub of Sydney commerce, shaping the city’s urban grid and Martin Place precinct. Later additions along George Street were designed by the first man to hold the title of Government Architect, Walter Liberty Vernon. In 1942 the clock tower was demolished to reduce its visibility as a war-time air target, but it was rebuilt in 1964. The GPO served as postal headquarters until 1996, when the site was privatised and radically transformed.

The Buchan Group designed a 26-level office tower and the 31-level Westin Hotel. Heritage architects Lucas Stapleton Johnson helped integrate these around a glazed Grand Courtyard, and conserved the GPO’s elegant sandstone facade, colonnade and famous clock tower. Still virtually intact today, this facade is heritage-listed on both the state and commonwealth Heritage Register and New South Wales State Heritage Register.

In 2016 architects Fitzpatrick + Partners completed a refurbishment of levels 1-7 for Macquarie Group where they cut through concrete floors to connect each level using the visual theatre of an Escher-like staircase within a seven-storey atrium.
