4 Mwrog Street

4-8 Mwrog Street form a group of buildings. This is a long, two-storey structure with slightly advanced gabled bays at each end, the left one being slightly inset, creating an overall appearance of seven windows. The exterior is roughcast with lined-out render on the ground floor of the central section, and it has slate roofs topped with a banded brick stack from the late 19th century on the left gable end.

Between the advanced gables, there is a five-window range, although the upper storey windows do not align with those below. Architectural details include a modillion eaves cornice and scalloped barge boards with finials on the gabled bays. There are three entrances featuring uPVC doors with uPVC panels above, which have replaced original four-panel doors with overlights. The windows have been renewed with twelve-pane wooden sashes. The gabled bays contain tripartite sashes, except for the upper right bay which has a pair of sashes. In the main range, there are doorways to the left, left of centre, and right, with two windows to the right of centre. The left window on the upper storey is smaller.

The west gable end is constructed of random stone with brick quoins, while the east gable end is adjacent to the Park Place Hotel. The rear of the building is made of brick, with the right-hand part slightly set back and primarily featuring uPVC windows. The interior has not been seen.
