11 Church Street

11 Church Street is part of a two-storey terrace of five single-unit cottages located in Llandderfel. Each cottage features a single window unit, except for no. 8, which has a two-window unit that provides access to a rear yard. The cottages are constructed from local slatestone rubble with slatestone lintels and have a slate roof that steps up slightly at no. 9 and continues from there. They feature shared rubble chimneys, with an additional end chimney at no. 8, along with weathercoursing and slate cornice bands.

Each unit, except for no. 8, has an entrance with a single window to the ground and first floor either to the right or left. The entrances are on the right for all units except for no. 11, which has its entrance on the left. The doors are boarded, with nos. 9 and 12 having glazed panels, while no. 8 has a modern glazed door. Nos. 9 and 12 feature 19th-century nine-pane sashes with horns on both floors, with the first-floor window of no. 12 breaking the eaves and set within a small gabled wooden dormer; this unit is also rendered. No. 8 retains original unhorned twelve-pane sashes. Nos. 10 and 11 have nine-pane sashes on their first-floor windows, with larger small-pane windows on the ground floor—fifteen-pane for no. 11 and twelve-pane for no. 10, which also has an inserted narrow eight-pane window to its left. Both nos. 10 and 11 retain narrow rectangular overlights above their doors, an original feature.

The interior was not inspected during the survey.
