Description

Trem Wawr is a two-storey terrace consisting of six former single-window cottages, with the leftmost unit being a larger two-window structure. The cottages are built from local igneous rubble and feature a continuous medium-pitched slate roof, supported by six chimneys made of buff stock brick, which have cornice banding and offset dentilations. The ground floor has cambered brick openings, while the first-floor windows are positioned under the eaves.

No 1 is a two-window unit with a central entrance and a large left-hand window, indicating it may have originally been a shop. This unit has a modern door that is not in keeping with the original character and uPVC windows designed to mimic small-pane cross-windows, along with similar faux two-part, six-pane casements on the first floor. Nos 2 and 3 are also two-window units; No 2 features a part-glazed 20th-century door and uPVC windows that imitate four-pane designs on the ground floor and two-pane casements above. No 3 retains its original boarded and framed door, along with small-pane, timber-framed cross-windows that have wrought iron opening lights.

To the right of No 3 is a former cottage that has been divided and incorporated into Nos 3 and 4. Originally, this and the other units in the row were one-window cottages. The former entrance to this cottage has been reduced to a plain-glazed cross-window, now part of No 3. The adjacent window, which is now part of No 4, is a plain-glazed, two-pane 20th-century casement, and this unit features a plain 20th-century door and a similar window to the right, with plain two-pane casements on the upper floor. No 5 retains its original door and upper floor window, while No 6 has uPVC cross-windows and a modern part-glazed door that is out of character with the rest of the terrace.

The interior was not inspected during the survey.
