4 Garreg Terrace, A4085

4 Garreg Terrace is part of a terrace of five cottages and the Brondanw Arms public house located at the northeast end. The buildings are constructed of rubble with a continuous slated roof, using old slates for the Brondanw Arms. The cottages, numbered 1 to 5, feature low rubble forecourt walls, while the Brondanw Arms is set behind low rendered and pierced block walls. Cottages 1 and 2 are rendered, while the others are whitened. There are plain shared end chimneys, with the chimneys of the inn being larger.

There are 20th-century storeyed additions at the rear of cottages 1, 3, 4, and 5, and a single-storey rear lean-to addition at cottage 2. The entrance to the cottages features a modern boarded door, with square, 9-pane sash windows on the right side at both the ground and first floors, and 16-pane steel-framed windows on the left side on both floors.
