4 Chapel Row

4 Chapel Row is part of a two-storey terrace consisting of six one-window units located in Llandderfel. The buildings are constructed from local slatestone rubble, featuring slatestone lintels and rough-dressed quoins on number 1. They have a continuous slate roof with a tiled ridge and shared brick chimneys, except for the left chimney, which has been restored at the upper courses. Each unit has an entrance with a single window to either the right or left side on both the ground and first floors. The entrances for numbers 1, 2, and 4 are on the left, while the remaining units have their entrances on the right. Numbers 5 and 6 still have their original flush four-panel doors, and there is a similar door on the far right leading to a rear yard; the other doors are modern and part-glazed. Numbers 1, 3, 4, and 5 retain narrow rectangular overlights, which are original features. All units, except for number 2 and the ground-floor window of number 3, have original recessed, unhorned 12-pane sash windows; number 3 has a modern wooden bow window instead. There is a modern slated canopy porch added to number 3. The interior was not inspected during the survey.
