Harcourt Terrace Wesleyan Methodist Chapel, including schoolroom and front railings

Harcourt Terrace Wesleyan Methodist Chapel, which includes a schoolroom and front railings, is constructed of coursed Pennant rubble with ashlar detailing and has a slate roof. The chapel features a three-bay gabled front, with the bays separated and finished by thin pilaster strips. The gable is corbelled in a Lombardic style. In the center, there is a neo-Norman triplet with shafts that have scalloped capitals. Each outer bay has a small roundel that lights the gallery stairs. The ground floor center has a row of five round-arched lancets, which date from the early 20th century when the central entrance was replaced by the current round-arched doors in the outer bays. These doors are adorned with stone voussoirs and feature half-glazed doors with fanlights.

The schoolroom has a three-bay gabled facade made of similar stone to the chapel, also with ashlar detailing and a slate roof. It has round-arched windows on both storeys, complete with ashlar heads and keystones, and marginal glazing. There is a roundel on the gable with keyblocks, and a 20th-century door is located on the ground floor to the left.

Both the chapel and schoolroom are fronted by cast iron railings, likely made locally. These buildings are slightly set back from the street, with openings in front of their entrances. The railings feature decorative finials, and the strengthening posts have an entasis and urn finials.

Inside, the rectangular galleried space boasts a striking early 20th-century gallery front that is deeply splayed at the front end and richly decorated with plaster festooned with vines, set against a background of shields linked by branches at the top and a strap-like band in the middle. At the pulpit end, the gallery curves inward and continues similarly along the front of the choir gallery. The interior features cast iron columns with bell-type caps. The communion table, rails, and flanking seats are designed in the Art Nouveau style, with tall pierced backs. The balustraded pulpit reflects a Romanesque style similar to the facade, featuring carved capitals. A large semi-circular arch at the rear of the pulpit opens onto stairs leading to the choir gallery and organ chamber, which are situated above the vestries; the organ was brought from a chapel in Ferndale. At the rear, there are two stained glass windows dating from 1904, possibly indicating the date of remodeling. The interior also includes half-glazed lobby partitions and a modern segmental ceiling.
