Y Graig

Y Graig is a mid-19th century pair of two-storey houses featuring two windows each. They are constructed from coursed rubble masonry and have a moderately pitched slate roof with close eaves and plain bargeboards. The houses have dressed stone stacks positioned lengthwise to the ridge and at the center of each house, topped with heavily moulded caps and water tabling.

Each house has a centrally placed gabled dormer with raking gable copings on kneelers and a finial. The windows are stepped tripartite designs with small panes and a tilting center light. The left side of both houses has a 12-pane sash window, while the right side features a 16-pane sash window on the first floor. The ground floor has larger 16-pane sash windows on the right, and the doorways are located to the left, each with rectangular fanlights, with Roslyn's fanlight being decorative. The doors have six deep narrow panels.

At the rear of Roslyn, there are two 12-pane sashes on the first floor and a gabled outshot on the ground floor. Y Graig has an unsympathetic large flat-roofed dormer and a modern Velux window. There is also a two-storey lean-to outshot to the right, with a 16-pane sash window to the left.
