Description
4 Glanrhos Terrace is a pair of two-storey terrace houses built in the 19th century. Constructed from mortared rubble masonry, the buildings feature large stones as quoins and lintels. They have a slate roof, with each house displaying a broad rectangular stack with dripstones and capping at the left (north) end. The windows are slightly recessed, 6-pane horned sash windows with slate sills, while the ground floor windows at the rear are smaller. The main facade faces away from the road and overlooks gardens to the west, with mirrored pairs along the range. Each house has a two-window arrangement and a boarded door situated under a slate-roofed porch canopy. At the rear, there is a single window on both the ground and first floors, offset to the south. Notably, at the right (south) end of the terrace, this house has its doorway offset to the left (north). The interior was not inspected during the survey.
