189 South Street, Perth

189 South Street in Perth is a four-storey and basement corner tenement building designed by McLaren & Mackay between 1900 and 1901. The structure features three bays on the main façade and two bays on the side, with a public house located on the ground floor. A prominent canted corner bay includes three windows, and an octagonal tower with a finialled slated spire rises above, breaking the eaves. The exterior is constructed of ashlar stone, with rubble at the rear. Notable architectural details include a chamfered base course, a cornice at the ground level, cill courses, a band course, a deep cornice, and a pierced balustrade at the attic level. The windows are framed with moulded architraves, and some upper levels feature raised quoins. The basement has regular openings.

Additional features include pilasters at the ground level that support decorative cartouches. The first-floor windows in the corner bay are adorned with scroll pediments. The third floor has a corbelled bay with Ionic columns and round-arched window openings that are key-stoned.

On the elevation facing South Street, the far-right bay has a broken round-arched pediment topped with a central obelisk at the attic storey. The upper floors predominantly have six-pane over plate glass timber sash and case windows, while the ground floor features plate glass windows. The roof is covered with grey slates, and wallhead stacks are present.

The interior of the public house, observed in 2009, includes an internal timber stair leading to the flat above, a timber bar counter, Corinthian columns, and decorative cornicing.
