Brickwork was by A. Mansfield, plastering J. Jamieson and joinery Arthur Foote Ltd.[1] The Returned Soldiers and Sailors Imperial League of Australia (RSSILA) was formed in 1916 and a branch opened in Ipswich in September 1917.

[1] The entrance portico is approached by flanking balustrade quadrant walls at street level, with stairs leading up to the ground floor.

[1] The memorial chamber was originally naturally lit from above through a large rooftop lantern and central light well with encircling gallery at first floor level; this is now closed over.

A silky oak timber staircase leads down to the basement which contains meeting rooms and an office and has a separate entrance on the northern side from the adjacent park.

The main meeting room features a large semi-circular window, originally the location of a stained and coloured glass memorial now removed.

[1] The internal detailing of the building is not elaborate, and includes silky oak joinery, painted plasterwork and ceilings of fibreboard with geometrically placed cover battens.

The Memorial Hall Ipswich, built in 1920–21, demonstrates the patriotic fervour associated with World War I and the community's identification with the goals of the "mother country" Britain at this period in Queensland's history.

The interior is generally intact and with the trend towards conversion of the larger halls for service clubs with poker machines, this is becoming rare.

Since 1920, the Memorial Hall has had a special association with the RSL and with various allied groups such as Legacy, Women's Auxiliary and War Widows.

It has a strong spiritual and social association with the general community and returned service personnel as the focal point for Anzac and Remembrance Day commemorations.

It has strong associations with the wider community because of its use for other purposes such as the city library, blood bank and as a place for meetings and social events.

The design of the building is the work of recognised local architect George Brockwell Gill and is a fine and typical example of his style at this period.
