Description
50 Harbour Street is an earlier 19th century, two-storey house with a rectangular plan. It is constructed from painted coursed tooled sandstone, featuring ashlar margins and quoin strips.
On the northwest (principal) elevation, the doorway is offset to the outer right, with a small window to the left of the door and a window above it on the first floor. There is a bay to the left that has windows aligned on both the ground and first floors.
The northeast elevation is attached to No 48, while the southwest elevation presents a gable end.
The house has varied timber sash and case windows, a grey/brown slate roof, stone skews, and an ashlar gablehead stack on the north side.
The interior was not seen in 1997.
