Registrar-General's building, Heritage-listed government office building in Sydney CBD, Australia

The Registrar-General's Building is a three-storey Neo-Gothic sandstone office building with an attic storey and basement, steel-framed with reinforced concrete floors and a slate-covered steel roof. Its facades have Gothic window detailing and carved gables; three large gables face Prince Albert Road, flanked by castellated corner turrets, and the Queen's Square facade has a small gable flanked by two turrets on each side.

The building was designed by Government Architect Walter Liberty Vernon and opened in 1913 as the central office for land titles registration. It was constructed during a period when Sydney was modernizing its administrative functions and centralizing record-keeping facilities in the city.

The carved initials of stonemasons Colin Hudson and Herbert Charles Hudson remain visible on the building's exterior, marking their individual work. These marks tell the story of the craftspeople who constructed the structure.

The building is located in the Sydney CBD and easily accessible via Prince Albert Road, situated near other government offices for clear orientation. Its location makes it straightforward to view the structure as part of a walk through the business district.

The keystone above the main entrance carries the entwined numbers 1912, marking the year the facade was completed. On the western return wall near St Mary's, the initials CH are carved into a string course boss at about second-floor level, for stonemason Colin Hudson; his father Herbert Charles Hudson's initials HCH appear nearby on a small octagonal turret.
