This building, designed by J. Melville Miller of Montreal and constructed by William I. Bishop Ltd., opened in 1926. It included a post office on the main floor, the customs office on the lower floor, and the court house on the top floor.

The building is a concrete structure with poured in place concrete exterior walls, floors, and columns. The exterior finish is painted concrete, and the interior finish is plaster with ornamental mouldings and pilasters. There is a marble stairway, and originally there were to be other marble features, such as black Missisisquoi marble door thresholds. The award for this project calls attention to the existence of a great variety of historic poured-in-place concrete buildings in Newfoundland, many of which are still in good condition and worthy of preservation or adaptive re-use.

Over the years, the Public Building at Corner Brook had many other uses. It was subsequently owned by Bowaters, the government, the railway and Newtel Communications. Newtel conveyed the property to the City of Corner Brook. The building was also used for the jail scene in Gordon Pinsent's film, The Rowdyman.

In 1997 the City signed a stewardship agreement with the Corner Brook Museum to house the city's first museum. The Society received funding from HRDC for restoration work, and also support from Newtel, the City of Corner Brook, ACOA, and the Downtown Business Association. Vacant for several years, the building was starting to deteriorate.

The work included exterior and interior restoration and upgrading of services and amenities to meet present day building code requirements. Original plaster mouldings were restored, as well as the marble staircase and the coat of arms over the front entrance.
