No. 20, Parliament Street

No. 20 on Parliament Street is a remnant of a large police station that originally had its main elevation along Alfred Gelder Street. Built between 1902 and 1904, it was designed by Joseph H. Hirst, the City Architect. The building is constructed of brick with ashlar dressings and a rock-faced granite plinth, though the roof and stacks are not visible.

This building is designed in the Baroque Revival style and features a plinth and ground floor with banded rustication, a moulded dentillated cornice, and a coped parapet. It has two storeys and a three-window range. The front is asymmetrical, with an entrance bay on the left that includes a semicircular first-floor balcony with balusters and a segment-headed cross casement window with a Gibbs surround and keystone. Above this, there is a recess flanked by pilasters, topped with a dentillated broken segmental pediment that contains a blank cartouche supported by female figures.

The ground floor features a cove-moulded round-arched doorway with fielded panelled double doors and a glazing bar overlight. To the right, the recessed first floor has two segment-headed cross casements with Gibbs surrounds and triple keystones, each flanked by engaged blocked Ionic columns. The ground floor also includes two round-headed cross casements with rusticated surrounds, moulded sills, and multiple keystones.
