House adjoining Penarth Independent Chapel

The building comprises a chapel and a house adjoining Penarth Independent Chapel. The chapel was originally built in 1789 for the Independent congregation, with significant alterations and rebuilding in 1838 and 1847, followed by a restoration in 1906 when the attached house was added or largely rebuilt. A stone above the entrance records these dates.

The house has colourwashed brickwork to the front, later roughcasted, and a slate roof. It is constructed of hard red Ruabon brick, featuring one gable chimney stack and one central stack. The chapel is rectangular with a central entrance at the southeast gable, leading to the side of the chapel room. A pair of doors with a four-paned overlight are set in a fluted doorcase and panelled reveal, replacing an earlier blocked door to the left. Six three-light windows with pointed lights are on the southwest elevation; the spandrels have flashed glass. The two central windows are larger, with double transoms, and are set at mid height, flanking the internal pulpit. Two smaller windows are beneath the eaves, with the other two positioned below them, creating a symmetrical facade. An attached house to the northwest is two storeys in height, with a two-unit plan. A porch has been added over a later door against the wall of the chapel, and a second, boarded door is located near the northwest end. The house has paned timber windows.

The chapel interior appears to date from 1906, although the gallery structure may be from 1847. The walls are plastered, and the ceiling features diagonally set boarding with ceiling vents at the junction of the panel ribs. The pulpit is high against a panelled and gabled backboard, centrally positioned between the windows on the southwest wall, and is cantilevered, with a balustraded front. Brass gas lights with globes are positioned on the front corners. The "Sedd fawr" (a traditional designation for important seating) also has close-set balustrading on top of the enclosing panelling. The main chapel floor has raked seating, with pews numbered 1 to 27. The three-sided gallery has pews numbered 28 to 45, is splayed at the angles, features a panelled front, and is supported by seven cast iron tapered columns.

The buildings are listed as a well-preserved country chapel with a fine interior from the early 20th century and with its adjoining Minister's house.
