11, King Street

This is an office building, originally built as insurance company offices between 1880 and 1890 by Alfred Waterhouse for the Prudential Assurance Company. It was restored and converted in 1991. The building is constructed of red brick with a granite basement and terracotta dressings, and has gabled and hipped plain tile roofs. It is designed in a Flemish Renaissance Revival style.

The exterior features a plinth, sill bands, ground floor and eaves cornices, and a latticework balustrade. The acute-angled corner block has three storeys plus a basement and attics, with three bays by five. Most windows are cross casements with elaborate terracotta surrounds. The corner entrance bay has an elaborate opening with steps leading to a recessed door. The opening is framed by pilasters, featuring a central figure in a niche, flanked by shields and small mullioned windows, all beneath a cornice. Above this, two floors are present with double windows and a pierced balcony. Above again sits a square tower consisting of two stages, with corner turrets and spires, culminating in an octagonal main spire with patterned leadwork and a finial. This spire features lucarnes and a tier of bell openings. Curved double bays are on each side, featuring a central pilaster, four windows on the lower floors, two windows above, and a gabled dormer. The basement is characterized by four openings. The returns, with five bays each, are similar to the main block, featuring regular courses of windows and gabled dormers. Two round-arched basement openings are found in each bay. The emphasised end bays have similar fenestration, as well as round-arched doorways and elaborate gabled dormers topped with square-spired fleches.

The interior retains some original features, including a round stairwell with a stone spiral stair and wrought-iron railing, and a similar minor stair. The entrance hall contains a moulded glazed tile panel and three door surrounds. The banking hall features textured tiling and a strapwork panelled ceiling with enriched dentillated cornices. There are two chamfered round arches leading to a similarly tiled corridor. A faience tile fireplace with an arcaded canopy, and a clock dated 1895, are also present.
