It was designed by Chris A. Smith and built in 1927, and was added to the South Australian Heritage Register on 21 October 1993.

[5] The additions provided for a new stage and dressing rooms, new library and reading room in front, a council chamber and clerk's office, and a new classical facade replacing the previous "blank wall", at a cost of £1,200.

[9][10][11] Christopher Arthur Smith,[12] an architect who designed a number of South Australian public buildings, had completed a design for the new hall by June 1926: located adjacent to the old hall, it was to have five office fronts, a subscribers' room, a public reading room, a town clerk's office, a council chamber, and a hall seating 1,100 to 1,200 people, at an expected cost of £11,705.

MP George Jenkins described it as "the finest hall he had seen in any town of the same size.
