Description

4 Clwyd Street is a three-storey building constructed from coursed and squared rubble, topped with a slate roof featuring end wall and axial stacks on either side of the ridge line. The main elevation facing Clwyd Street has a five-window range, while the return to Russell Road has a four-window range. The entrances are framed by moulded architraves and feature entablature hoods supported by brackets. Flanking the doorways are intact two-storey canted bay windows at Nos 3 and 4, which include 2 and 4-pane sashes separated by fluted corner columns, panelled aprons, and plain cornices. At No 2, the ground floor has been altered with a shop front from around 1950 that wraps around the bay window and extends across the Russell Road elevation, although the original detailing remains visible in the upper storeys. The upper levels feature four-pane sash windows above the doorways, as well as on the first floor of the Russell Road elevation and in the second storey, where they are topped with plain stone lintels. The eaves overhang is supported by moulded brackets.
