Garrison Theatre, 2 Market Street, Lerwick

The Garrison Theatre, located at 2 Market Street in Lerwick, is a former drill hall designed by William Arthur Baird Laing and completed in 1903. This building features two storeys and an attic, showcasing a three-bay Scots Baronial style. The exterior is constructed from stugged squared and snecked sandstone, accented with concrete-covered ashlar dressings. Notable architectural elements include a base course, long and short quoins around the windows and corners, and projecting cills at the windows.

On the west elevation, there is a central, architraved and corniced six-panel, two-leaf timber door topped with a four-pane fanlight and a datestone above. The ground floor has bipartite windows in the flanking bays, while a dormer with a bipartite window and a stone crowstepped dormerhead is positioned to the right of the centre, breaking the eaves. The left bay features a gable with a bipartite window on the first floor, and the bay to the right rises in a tower, breaking the eaves at the southwest corner, which is corbelled out to support a crenellated parapet above.

The south elevation presents an asymmetrical three-bay layout, with the hall extending to the right. It includes a raised door opening at the centre bay on the ground floor, flanked by windows, and a first-floor window in the left bay that is part of the corner tower. The right bay has a bipartite dormer window, offset to the right, which also breaks the eaves with a crowstepped stone dormerhead. The hall elevation extending to the right is mostly obscured by a modern addition.

The north elevation consists of a two-bay end elevation on the principal front to the right, featuring a crowstepped chimney gable with windows flanking the centre. The hall extends to the left, with its ground floor obscured by a modern lean-to addition.

The building has modern timber windows with multi-pane uppers and plate glass lower sashes, and it is topped with purple slate roofs that are piended on the front block and gabled over the hall. The profile includes cast-iron gutters and downpipes with decorative hoppers and brackets. The interior was last seen in 2008 and has been modernised.
