Muttama Hall is a timber-framed building, clad in corrugated iron. The front facade is in the Classical style, popular around the 1920s, and features a timber-framed veranda over the front doors and two windows. Inside is an elevated stage, with dressing rooms located behind. The walls are lined with the original cypress pine boards. There is also an attached skillion, which houses a kitchen and supper room.
The hall was opened at a gala ball on 20 May 1925, which was "beyond all expectations a brilliant success" (Cootamundra Herald, 26 May 1925).
Construction was funded by First World War veterans and the local community. Despite the ensuing Depression, the debt was gradually paid off by the community, with only £240 outstanding by September 1938.
The hall houses the Muttama Great War Roll of Honor and the Muttama First and Second World Wars Roll of Honour. It is located diagonally opposite the Muttama Recreation Ground First and Second World Wars Memorial Gateway.
Major conservation and restorative works were completed in 2019, in accordance with conservation action and master plans, designed to enable the hall to be used for national commemorative events, as it had been since 1925. The original mini orb iron cladding was retained, as were the brick fireplace and chimney on the western end of the kitchen. The flooring in the main body of the hall was replaced with new Australian hardwood boards. Additional works to replace the kitchen and supper room are to be completed in 2021.
The hall is the site for Anzac Day commemorative services, and is sometimes also used for Remembrance Day and Australia Day events. Access inside the hall is by appointment/tour.
