were marked on their first floors by a three-light window with two large masonry mullions with segmental brick arches. The corner pavilion has two arched windows in its first storey, with a recessed wall layer inside the arch framing two narrow arched windows with a roundel between their arches. Above that was a single storey extension to form a clock tower. This was separated from the first floor pavilion below by a dressed panel with a set of slots, and a coffered wall with a clock face inside the coffer facing Wharf Street, and a circular vent facing Bazaar Street. This level had a coffered frieze, boxed eave without bracketing, and a simple low-pitched pyramidal roof. Above this roof was a flagpole with a ball roof finial at its base. The chimneys were in plain masonry with a cornice, string course necking and broadened base. The windows were small-paned frames, in double-hung sashes on the first floor quarters elevations, broadened at the tower base into fully open arches; all upper windows on the Bazaar Street side now have heavily scaled concave canopies. The 1878-9 alterations included a loggia enclosure, to add more rooms and gain better natural lighting. The tower was extended; the rear was also extended by about a third, and the north flanking bay was absorbed into the recessed elevation next to a new projecting wing. The Bazaar Street side was terminated by a new bay reproducing the old flanking pavilion in elevation, and a terminating bay of large door width flanked by two corners with rusticated quoins. The original hipped roof was replaced by a gable-hip. This arrangement needed more sun protection, so in 1886, during JJ Clark's term as Government Architect, the pavilions, tower and bays were then all linked by a deep sheltering verandah, carried on turned columns, rounded at the corner, with two low gables fronting its fascia directly in front of the corner tower bays. The tower's previous top level, housing the clock, was retained as a vented level with the circular vents of the original tower being carried all the way round, and with a new clock level including clock faces to all four sides, framed by an arch moulding carried on two squat pilasters flanked by a Corinthian column at each corner. The tower was then topped by an Italianate balustrade with waisted balusters. The original pyramidal roof and ball-based flagpole
