Mechanics Institute Number 9 with Attached Meeting Hall

The Mechanics Institute, now a house and meeting hall, was built between 1844 and 1845. It features deeply-coursed, horizontally-tooled sandstone and a Welsh slate roof. The building is two stories high with a three-bay symmetrical front and a tall single-storey wing at the center rear, which has an addition to its right. The exterior includes a chamfered plinth and a chamfered band beneath the ground-floor sill level, along with clasping corner pilaster strips.

Access is via three stone steps leading to a 20th-century double door set in a double-chamfered surround with a Tudor-arched lintel and hoodmould. Flanking the entrance are three-light casements with horizontal glazing bars, all in deeply-chamfered surrounds. The first floor has three similar windows, with a hoodmould above the central window. A chamfered band runs beneath an embattled parapet that steps up at the center, above a blank shield. The pilaster strips rise to form embattled turrets. The left return features a blind Tudor-arched opening on the first floor, a raking gable parapet, and a rear turret. The wing has tall, chamfered lights with renewed casements and end turrets.

Inside, the ornate roof trusses in the rear wing have cusped-headed subdivisions. There is a 20th-century entrance lobby on the left return and additions to the rear right corner that are not of special interest.
