Description

This is a pair of houses, formerly police dwellings, attached to the Police Station, built in 1904. They are made of rock-faced Portland stone with slate roofs and are set back from the Police Station's frontage. The buildings are two stories high and have one window on each side. All windows are tripartite sashes with flush chamfer surrounds and stone mullions, with the central upper sash unit featuring two vertical glazing bars. On the left and right sides, there are good 19th-century panelled doors beneath small plain transom lights, all in flush chamfer surrounds. The houses have a plinth, a moulded mid string that connects with adjacent properties, a stone eaves course, and raised coped verges on both ends and at the party division. There are brick stacks on the rear slopes and projecting rear wings.

In front of the property, there is a boundary wall made of regularly coursed rock-faced stone, rising about 2.2 meters with a plain parapet, which serves as a retaining wall behind the pavement. To the left, there are seven stone steps that return towards the Police Station. This pair of houses is part of a significant composition with no external changes and is important for the skyline as seen from the approach road from Victoria Square below.
