Description
Cwrt yr Harbwr is a two-storey building made of rubble stone, featuring large slate-stone blocks arranged in rough courses, topped with a hipped slate roof. It has a stone ridge stack located to the right of the center and at the right end. The front of the building faces northeast, where the two original dwellings are situated on the right side and still have their original openings. The central and left sections of the building, which served as a warehouse, mainly feature inserted openings. All the inserted or replaced windows are small-pane horned sashes.
The gabled center has glazed doors in earlier openings on both storeys, flanked by windows for apartments Nos 3 and 4. At the left end, there is a balcony supported by steel posts and a glazed door beneath a gable. To the right of this is a lean-to porch with glazed doors leading to apartments Nos 5 and 6, along with two additional windows further to the right, and two upper-storey windows, one of which is a flat half-dormer. A full-height vertical joint to the right of center indicates that the warehouse and the dwellings were built at different times.
The double-fronted house (No 2) and the single-fronted house (No 1) have replacement doors, with the door to No 1 set in a slightly wider original opening. Notably, No 1 does not have an upper-storey window. The right (north) end wall of No 1 is constructed from slate-stone blocks laid in regular courses and features a central blocked doorway, which is unusually positioned directly beneath the stack. The nine-window rear elevation has replacement windows for the original dwellings on the left end, while the rest consists of inserted windows. A full-height joint separates the warehouse from the domestic section, and four additional full-height vertical joints suggest that there were originally open bays on this side of the warehouse. The building has not been inspected.
