Adam Street Garage And Adjacent Property To Left

Adam Street Garage and the adjacent property to the left is an institute that later became a theatre and is now used as a garage. It is likely the Literary and Scientific Institute built in 1841, as noted in Kelly's Directory of 1867. The building has undergone 20th-century alterations and is constructed of brick in Flemish bond with ashlar dressings and a Welsh slate roof. It stands two storeys tall and has nine bays facing Adam Street. The first two bays are slightly set back and feature a rounded corner at the left end.

The building has a plinth, and bays four to nine display full-height round-arched blind arcading with imposts and channelled arches that include drop keystones. Bay four contains double board doors, bay five has a blocked round-arched doorway with a divided fanlight beneath a channelled arch with a dropped keystone, bay six has double board doors, and bays seven and eight feature sashes with glazing bars beneath channelled wedge lintels with dropped keystones. Bay nine also has double board doors. To the left, bay one has a 4-pane sash, bay two has wide board doors beneath a concrete lintel, and bay three has double board doors below a blocked fanlight and a channelled round arch on imposts with a dropped keystone.

On the first floor, bays one and two have 16-pane sashes, and bay three has a 4-pane sash, all with channelled wedge lintels and dropped keystones. Between bays six and seven, there is a plaque that reads "Public Rooms." Above bays four to nine, a frieze bears vestigial lettering that reads "Theatre Royal." The building features a stack rising through the front pitch of the roof and an additional ridge stack.

The Chapel Street facade is also two storeys high with three first-floor windows. To the left, there are board doors in a partially blocked entrance beneath a 5-pane fixed overlight, with a 4-pane sash to the left. To the right, there are two board doors with divided overlights, one of which has "Theatre Royal" faintly discernible above it. On the first floor, there is a central board pitching door with two 4-pane sashes to the left, all featuring channelled wedge lintels and dropped keystones.

Inside, the former auditorium, now a garage, has a proscenium arch flanked by Corinthian pilasters, pilaster strips in the upper section of the walls, and several ceiling roses.
