3, Princes Street

No. 3 Princes Street is a wide-fronted house in a row, now used as offices, dating from the mid to late 18th century, with some reconstruction from the late 20th century. It is constructed of limestone ashlar, and the roof is not visible. The building has a party boundary aligned with Monmouth Street, and its facade is set at a significant angle on a trapezoidal site.

The exterior features three storeys and a basement, with five windows, all of which are twelve-pane sash windows set in moulded architraves on the second and first floors. These upper-floor windows have cornice hoods above pulvinated friezes and a sill band at the first floor. Windows two and five on the upper floors are blind. The ground floor has sashes in plain reveals, with bay four featuring a sixteen-pane window and bay five being blind. The heads of the basement lights have bars and are located in bays one and four.

There is a central wide panelled door with a transom light, accessed by three steps, and the reveals are not square, following the alignment of the party wall. The building has a plinth and a full-width concrete band above the ground floor, which replaces a wooden lintel, along with a platband, moulded cornice, blocking course, and parapet. Each end of the building has high coped gables with deep ashlar stacks. The interior has not been inspected, but a former listing mentions a display window to the left of the entrance.
