Description
135, 137, and 137B Mwrog Street form a group of two-storey terraced houses. They are built from coursed blocks of squared stone and topped with slate roofs, featuring brick stacks. The openings have segmental heads made of stone voussoirs, except for the right-hand bay of 137 and 137B, which have cambered stone heads. The windows are wooden casements, either 2-light or 3-light.
At number 135, there is a ridge stack on the right. The left side has a 20th-century part-glazed wooden door, while to the right is a 3-light wooden window with a central opening casement. There is a similar window directly above. On the left, there is a vehicular through-passage with an elliptical head of stone voussoirs and a brick side wall to the right. Above the through-passage, there is a small uPVC window.
The interior has not been seen, but it is said to have had irregular exposed timbers from the 18th century or earlier.
