Victoria Halls, Sinclair Street, Helensburgh

Victoria Halls is a 2-storey, near-symmetrical, T-plan town hall built in the Scots Baronial style in 1887 by J and R S Ingram, with minor additions and alterations in 1899 by A N Paterson. The building is constructed of bull-faced, snecked, and squared cream sandstone with ashlar dressings, incorporating base and string courses. The windows are single, bipartite, and tripartite, with ashlar mullioned windows, and mullioned and transomed windows to the west elevation at the first floor.

The west (Sinclair Street) elevation features a segmental-arched, architraved doorway at the centre, with half-glazed, 2-leaf doors and a tall fanlight, flanked by moulded strip pilasters and narrow windows. A projecting balustraded balcony, supported on heavy console brackets with ball finials and a medallion of Queen Victoria, sits above. Tripartite windows are located flanking the central section, with a narrow window to the outer right and left. Three closely grouped bays at the centre of the first floor contain a tripartite window with a stepped hood mould, flanked by narrow windows, with a corbelled and crenellated parapet rising to a French pavilion roof, featuring brattishing and angle bartizans; the bartizan to the left has a conical lead roof. The outer bays have tripartite windows, crowstepped gables with angle bartizans, and one bartizan with a conical lead roof.

The south elevation exhibits a crowstepped gabled return with angle bartizans and an apex stack. Three windows are at ground level, and two windows are visible at the first floor. A lower, 2-storey link to the right contains a tripartite mullioned and transomed window at the first floor. A single-storey and attic pavilion is situated in the re-entrant angle, abutting the taller hall block to the rear. This pavilion features a blocked doorway to the left and a canted oriel window (1899) above, with a polygonal roof and swept eaves. The south return has a window to the left and a bipartite window to the right at ground level. A taller block to the right incorporates bipartite mullioned and transomed windows to the centre and left, a door below the central window, and a fire escape door to the outer right.

The east (rear) elevation displays five bipartite mullioned and transomed windows, divided by off-set buttresses, with one window to the outer right partly blocked. Later harled additions are visible to the right.

The north elevation demonstrates a gabled return, similarly detailed to the south elevation, with the exception of a door to the far left. A lower, 2-storey over basement link to the left includes a bipartite mullioned and transomed window at the first floor. An advanced, M-gabled block, divided by a single bay to the centre, is located to the outer left. Apex stacks and a taller piended roof are present behind the main hall. The basement level features a door to the centre, a bipartite window above and to the left at the first floor, a window to the centre at the second floor, and a bipartite window to the left. A return to the right incorporates a basement window to the centre, a bipartite window at the first floor, and a window at the second floor.

The interior features a columnar vestibule door with Glasgow/Art Nouveau style detail (1899) and compartmental plasterwork to the ceiling of the entrance hall.
