1. Terraced Row of 4 Houses oppisite Indepentent Chapel

This is a terraced row of four houses located opposite the Independent Chapel in Crugybar, built in 1867. The houses feature stuccoed painted fronts that are scored to imitate ashlar, with a slate roof and wooden soffits. The eaves on the left are bracketed, and there are four ridge brick chimney stacks. Each cottage has a narrow two-bay front. The house named Llysycoed has four-paned horned sash windows, while Minerafon and Annelfa have 12-pane hornless sash windows. All three houses have boarded doors.

The former Post Office has a three-bay front with upper 9-pane hornless sash windows and a 12-pane hornless sash window on the ground floor to the left. There is a wide shop window to the right, featuring a raised cemented architrave and original wooden panelled shutters, along with a central modified panelled door. To the right of the Post Office, there is a single bay store that is slightly recessed but shares the same roofline, with planked doors on each storey. A datestone between Annelfa and the Post Office reads "Built 1867 T.D." The left gable end is constructed of rubble.

The rear of the houses is limewashed rubble, with a 20th-century door to Llysycoed, a brick cambered head, and a 12-pane hornless sash window above it. Minerafon has a planked door and 6-pane 2-light casements, with similar heads. Annelfa features a planked door, a ground floor 4-pane horned sash window, and a 6-pane casement above, also with similar heads. There is a gabled rubble-built extension from around 1930 at the rear of the former Post Office, which has wide 6-pane sashes.

At the rear, there is an alleyway backed by a range of 19th-century single-storey rubble-built coal sheds with corrugated iron roofs, planked doors, and a 12-pane hornless sash window to the right. A brick chimney stack is located on the right gable, and there is a 20th-century garage attached to the left.

The interiors of the houses are small, with Annelfa being the most intact. It features a winding stick-baluster stair, a front parlour with an Edwardian mantelpiece and hob-grate, and flanking glazed cupboards. The former Post Office has simple shop fittings, and there is a sack pulley in the roof of the store.
