Bethel Chapel and attached cottages [Rhoslwyn and Bethel House)

The building comprises a chapel and two attached cottages, Rhoslwyn and Bethel House. It dates from 1836 and is built in a simple classical style with a rectangular plan, the chapel having a gable end facing the road. The cottages are lower in height and slightly recessed, running parallel to the road.

The road elevation is constructed of roughcast rubblestone, while the cottages are roughcast throughout. The chapel has very roughly coursed rubblestone, with buttered pointing to the right return, and is slate hung to the left return and rear. All elements have slate roofs. The chapel gable has central 6-panel double doors under a narrow overlight, set within a projecting surround with a moulded entablature. Flanking the doors are tall round-headed margin-light sash windows in moulded surrounds with keyblocks, with a continuous cill and impost band. A string course is broken by a moulded round-headed opening containing an oval-shaped window with spandrels. A slate plaque above the doorway is lettered "BETHEL/ 1836". A broken cornice to the corners and coped parapet gives the impression of a pediment to the gable, which has painted plaster decoration to its apex. The returns each have two square-headed margin-light sash windows behind the cottages and two similar, but narrower, sash windows to the rear gable end. A brick chimney is located on the left return, astride the ridge of the left cottage.

The two cottages are essentially mirror images of each other. They feature gabled half-dormers on either side of central half-glazed doors. The windows were originally 4-paned sashes; replacements have been made to the ground floor of Bethel House, and the lower left window of Rhoslwyn is now a projecting 20th-century shop window. Integral end stacks are present on both cottages, alongside single-storey lean-tos attached to their gable ends, the lean-to on Rhoslwyn featuring a 20th-century window projection to the front.

The chapel interior is plain, with a plastered ceiling and a higher section to the ridge, accompanied by a plain moulded cornice. The walls are plastered above a tongue and groove boarded dado. The space is furnished with slightly raking pitch pine benches and a simple set fawr. Behind the set fawr is a blind segmental arch with painted Gothic lettering – "MYFIYWBARAYBYWYD” above, and the words "DUW/ CARIAD/ YW” and "DUW/ A/ BYGOA”, vertically and in Gothic script with floral motifs, to the left and right respectively. Bethel House features a central 19th-century staircase with a turned newel post at the foot.
