Masonic Hall, Gilmour Street, Alexandria

The Masonic Hall on Gilmour Street in Alexandria was designed by John Archibald Campbell and completed in 1888. It is a single-storey and two-storey building over a raised basement, arranged in an L-plan with a keep and hall connected by a link wall and courtyard. The main block features a Scots Baronial style, while the rear wings exhibit Arts and Crafts influences. The exterior is constructed from bull-faced pink sandstone with red sandstone ashlar margins and dressings, and it is topped with a corbelled balustrade.

The south elevation facing Gilmour Street includes a two-storey, two-bay square-plan keep on the right. Access is provided by steps leading to the main door, which is framed by decorative cast-iron railings and tall cast-iron lamp standards. The door is enclosed by a scroll pedimented surround with a raised segmental-headed armorial plaque, and it features a boarded and studded door along with an inscribed frieze. To the right, there is a tripartite window with a relieving arch above, and another tripartite window in the basement. The first floor has two symmetrically placed windows, a large terracotta plaque at the centre, a balustrade, and bartizans. An advanced chimney breast is located to the outer right at the right return, accompanied by a large transomed and mullioned stair window and a terracotta plaque on the left. A corbelled three-stage round tower is situated at the left return. To the left, a three-bay symmetrical range features open segmental-headed dormerheads, a gable with a balustraded canted bay window, an aediculed window with a segmental pediment dated 1888, and a broad stack at the apex with a blind niche at the centre.

The west elevation facing Smollett Street is symmetrically arranged with three bays. It includes blind tripartite basement windows, three segmental-headed windows at the principal floor, and three large pedimented transomed and mullioned windows at the upper stage, topped with a thistle finial.

The windows throughout the building are leaded and multipaned, featuring 20-pane over 2-pane sash and case designs. The roof is covered with green slates, although some areas have been replaced with concrete tiles. The apex stacks are coped and feature niches.

Inside, the entrance hall, corridor, and large hall are adorned with painted panels by Harrington Mann, illustrating women's work and scenes from 18th-century songs. The large hall boasts a hammerbeam ceiling and a passage gallery, along with two ashlar chimneypieces styled after the 16th century; one is nearly full-height while the other is smaller and features a painted panel.
