Built of stone, rendered and lined out, the lower stage with horizontal V-rustication. Slate roof with 2 large ventilators, now missing. Central pair of doors with overlights set in the wide slightly projecting central bay and flanked by broad pilasters. Three small windows to the single narrow bay each side. Above a first floor moulded string, the central bay is flanked by paired Corinthian pilasters which support a heavy cornice and pediment. At the centre, the dedicatory inscription within a moulded frame. Central between the pilasters a round-headed paned window with keystone flanked by narrow square-headed lights. The front elevation returns both ends as a steep pitched gabled pediment flanked by wide pilasters, and a high set small window in a classical frame. The sides of the chapel have 4 bays of margin-glazed windows, the upper round-headed. The vestry at the rear is wider than the chapel on the E side and has a hipped roof, which projects forward over a porch.

The large chapel, seating approximately 600, has a gallery with a panelled front and modillion cornice curving around 3 sides supported on cast iron Corinthian columns, marbled in paintwork. Slightly raked seating. The set-fawr has benches with upholstered backs within galleried panelling, and a raised pulpit. Behind the pulpit, a classical arch on paired pilasters and pediment over. The walls are plastered and lined to resemble ashlar, with a dado below. Original facetted pearl light fitting set in the centre of the moulded compartmented ceiling, which also has plaster rosettes. Clock over the pulpit. The vestry is separated by a service range with a small meeting room, the vestry itself has a pulpit imported from Aberdovey (1874) and is partitioned by a glazed screen.
