Maindy and Eastern Workmen's Institute and Hall

The Maindy and Eastern Workmen's Institute and Hall is a former institute and library located on Church Road, with the hall entrance and frontage on Pryce Street to the left side. This building extends to the rear elevation of Bethesda Chapel. The institute and library frontage is constructed from coursed rock-faced sandstone, featuring painted ashlar dressings. It has ashlar end and ridge stacks with cornices and pots, and a Welsh slate roof with ridge tiles and a central dormer. The structure is three storeys high with a five-bay frontage. The two gabled bays with finials on either side of the entrance project slightly and include two-storeyed canted bays with pitched slate roofs. A string course separates the main storeys, with separate quoins for the bays and a plinth. All windows are horned sashes. Steps lead up to double five-panelled doors with a semi-circular overlight that has a leaded inscription reading 'Maindy and Eastern Workmen's Institute' within a central round-arched doorway under a steep gabled surround.

The side elevation consists of two bays of the institute, the hall entrance, and a seven-bay hall. The entrance bay features three large long four-over-four pane horned sash windows on the first floor above a triple arched entrance, with steps leading past a shutter to quadripartite glazed swing doors. The hall elevation includes pairs of blank window features separated by an ashlar mullion, with each lintel being chamfered and the floors divided by a moulded string course; there are also two side doorways. A lean-to bay at the rear has three small gabled cross bays with yellow brick dressings.

Inside, the hall foyer features two diverging staircases leading to a gallery, complete with moulded wreathed handrails, decorative metal balusters, two curtail steps, and a decorative panel with a circular motif. A terrazzo floor in coloured panels partly survives. The auditorium retains a moulded proscenium arch, a boarded dado, some four-panelled doors and door surrounds, and a gallery with a panelled front and bracketed soffit supported by nine cast iron piers. The ceiling has a cornice and braces, and the seating consists of metal-framed tip-up seats of various designs.
