Description
4 Smithfield Street is a three-storey terrace of industrial housing, likely built around 1830. It was originally a small woolen factory on the top floor. The building features a two-window facade for No. 3, which was probably the manager's house, and a one-window facade for the other units, with pairs of windows reflecting each other. The exterior is roughcast with a painted plinth and has a renewed slate roof with mostly rendered brick chimney stacks and wide boarded eaves. The property retains small pane sash windows, with 9 and 12 panes in Nos. 3 and 5. There are later half-glazed doors and two small windows at the left end, which once had a weaving loft door to the gable. The rear of the building has modern windows, and No. 3 is shallower than the others. There is a high revetment wall beyond the building, which is against the former castle mound.
