Llidiardau Chapel including adjoining Ty Capel

Llidiardau Chapel and the adjoining Ty Capel form a Victorian village chapel and manse group characterized by a simple and functional design. The chapel is constructed from local slatestone, featuring snecked, rough-dressed slatestone facing. It has a continuous medium-pitched slate roof with simple bargeboards at the oversailing verges. The manse section, located on the right, includes a squat brick chimney with simple cornicing.

The chapel boasts a symmetrical facade with outer entrances and paired central windows, all of which have flat slatestone lintels. The entrances are fitted with original 6-panel doors, while the tall windows are adorned with 8-pane 20th-century glazing and projecting slate sills. Centrally placed within the gable above the windows is a stone plaque inscribed with the dates 1811 and 1860. The sides of the chapel are three bays long, featuring tall windows similar to those on the facade. The rear has some corrugated iron cladding. A narrow paved forecourt is enclosed by simple railings at the front.

Adjoining the chapel on the right is Ty Capel, which consists of two sections, with the far right section set back slightly from the main block. The left section has an entrance on the left with a 20th-century part-glazed door and a rectangular overlight. To the right of this entrance are mid-19th-century 16-pane unhorned sash windows on both the ground and first floors, each with projecting slate sills. The right section also has an entrance on the left, featuring a 19th-century boarded door and a 2-pane rectangular overlight. The windows to the right are similar to those in the left section, but with iron-framed 20th-century glazing; the first-floor window has 2 panes, while the ground-floor window has 9 panes. A 20th-century wooden boarded lean-to is attached to the rendered right gable.

The interior was not inspected during the survey.
