89, King Street

89 King Street is a former house, now an office, built in the late 18th century and altered in the 19th century. It is constructed of coursed dressed sandstone with ashlar dressings and has a slate roof. The building has a double-depth, slightly wedge-shaped plan that narrows towards the rear, likely indicating infill development between adjacent structures. It stands three storeys tall with three bays, plus a cellar and attic.

The entrance is located slightly left of centre, accessed by two steps, and features a raised plain surround with a cornice. On the left corner of the first bay, there is a wide low doorway leading to a through-lobby, which has a wedge lintel. The third bay on the right contains a blocked cellar opening with ventilators. The first and second bays have 4-paned sash windows with raised plain surrounds, while the third bay has similar windows that are coupled on each floor. The roof includes a large flat-roofed inserted dormer, and a large late 19th-century brick chimney stack is situated on the right side. The rear of the building has not been inspected.

Inside, there is a dogleg staircase located unusually in the left front corner. This staircase features an open string, scrolled brackets, columnar newels, stick balusters, and a ramped mahogany handrail.
