Capel Annibynwyr Carmel, including front railed forecourt

This is a chapel built in the Italianate style, likely in the 19th century. It is constructed from squared rubble stone with ashlar quoins and dressings, all set beneath a slate roof. The chapel's three-bay west-facing facade features a central recessed bay containing a central entrance. Above the entrance is a wheel window, set above a dentilled string course. The outer bays have two-light windows with quoined surrounds, bracketed sills, and voussoired segmental arched heads. The upper level windows are semi-circular arched, with two-light glazing and a roundel in the head. The entrance is accessed via a pair of panelled doors within an arched head, surmounted by an arched fanlight with a central roundel. The segmented arch of the fanlight is formed by voussoirs that increase in depth to create a semi-circular extrados. A small roundel slab, perforated with five holes, is set into the gable. Stepped stones leading up to the gable feature bracketed eaves, which terminate with pinnacles at either end and a central finial supporting an iron decorative feature. There are three windows on each side of the chapel, set over two levels; the lower windows have segmental heads, and the upper windows are round-headed.

In front of the chapel, a narrow forecourt is defined by a dwarf wall supporting railings between gate and corner piers. The railings have trefoiled heads.

The interior of the chapel is finely detailed and intimately scaled. A gallery runs around three sides, curving around the entrance lobby and supported by fluted cast iron columns. The walls are plastered, and the flat ceiling has moulded plaster ribs forming a cross pattern within an outer moulded plaster band, along with a plaster cornice. A roundel of leaves is positioned centrally. The "set fawr" enclosure is made of pitch pine, with an openwork top of a chain pattern, posts with finials and a raised pulpit accessed by symmetrical curved flights of six steps. The pulpit front is canted, with openwork side panels and a bracketed book desk. Brass brackets for oil lamps are located on either side. Behind the pulpit, pilasters rise to elaborate consoles supporting a semi-circular arched entablature, enriched with palmettes and egg and dart mouldings. The gallery features a moulded and bracketed beam supporting the front panelling, which incorporates perforated decorative panels. A central clock by Kibble of Gracechurch Street, London, is also located within the gallery, which provides three tiers of seating. The main chapel area contains a wide central block of box pews, and two side banks separated by walkways. The rear entrance lobby has angled side doors and a central glazed panel.
