Ffaldau Workmen's Institute and attached Billiard Hall

Ffaldau Workmen's Institute and the attached Billiard Hall is a notable building featuring a simple chapel-like front for the main Institute, with a lower parallel Billiard Hall wing to the left. The Institute is rendered and painted, while the Billiard Hall is constructed from coursed rock-faced sandstone with ashlar dressings, all painted to match the Institute, topped with an artificial slate roof. The gable end facade of the Institute is two storeys high with a basement, showcasing a three-window range of five-pane casements on the first floor, complete with moulded surrounds and quoins. A moulded cornice above marks the pediment, which features a circular ventilator at the apex and eaves quoin mouldings. The ground floor includes a tall central round-arched doorway adorned with moulded capitals, voussoirs, a keystone, and a surround; this doorway is flanked by a pair of one-over-one pane horned sash windows and has a recessed (replaced) double door with a semi-circular overlight above and a painted inscription band. Access to the main entrance is via one flight of steps, with another leading to the basement and Billiard Hall entrance, alongside a fire escape staircase on the right. The rendered gatepiers and iron railings enhance the entrance. The gabled cross wing on the right features similar mouldings on its gable front and round-headed margin-glazed windows on both floors.

The Billiard Hall wing has a low, single-storey gable end facade at street level, characterized by heavy quoins and a louvred keyed oculus in the pediment, supported by small piers that hold an elaborate finial in the form of a blind niche within a gable surround, flanked by scrolled brackets.

Inside, the main building retains its meeting rooms and library, with most mouldings intact on doors, windows, and ceilings, as well as double doors and a main staircase featuring a heavily moulded wooden balustrade on the right. The Billiard Hall remains in use, accessed from the basement level of the main building, which includes a well-preserved curved panelled wood and glass entrance booth. The hall is equipped with a series of full-sized tables, suspended lights, a parquet floor, a coffered ceiling in the fireplace recess, a brown glazed tile fireplace, ten-pane metal-framed windows with top-opening casements, and a wide coved main ceiling with roof lights.
