Hoff's other public sculptures in Sydney included a bas-relief of Mercury in Transport House, York Street and several sculptures in Emil Sodersten's City Mutual Life Building in Hunter Street. However, in spite of his obvious success, Hoff was unable to shake the controversy about the unexecuted ANZAC Memorial sculptures. It remained with him until his early death from pancreatitis on 19 November 1937. Builders and contractors The Trustees specified that the memorial must be built of Australian materials and by Australian workmen. Having been encouraged to give preference to returned servicemen, the contractors Kell & Rigby applied to the RSSILA Labour Bureau for their workers. Also working on the ANZAC Memorial were numerous sub-contractors. These professionals and artisans included structural engineers RS Morris & Co Ltd, masons Melocco Bros Ltd who carved the wreath around the Well of Contemplation, Messrs Loveridge and Hudson Ltd who prepared the granite facing on the outside walls, JC Goodwin and Co Ltd who supplied the amber glass, Art Glass Ltd, which completed the sandblasting, and T.

The London firm of Morris Singer & Co Ltd cast central sculpture and bronze panels over the doors but the flame surrounding the sculpture and the bronze grilles on the lower windows were made in Australia by Castle Bros, while Kell & Rigby themselves produced the bronze nails studding the doors. Homebush Ceiling Works made the ceilings and supplied the 120,000 stars for the dome, the latter being gilded by A. Zimmerman. Kellor and Yates completed the plasterwork. The Electrical and General Installation Co was responsible for the electrical installation and Nielsen and Moller made the light fixtures. Later, Dellit was able to persuade the City Council to supply temporary floodlighting for the building, a service made permanent in 1938. Changes in the course of constructing the ANZAC Memorial Originally, Dellit wanted the memorial to be built of sandstone or synthetic granite on an 18-inch base of Bowral trachyte. However, the building was actually constructed in red granite from quarries near Bathurst, NSW. The podium and semi-circular stairs were faced in granite; and the terrace was formed in terrazzo. In 1932 Dellit incorporated four stones from battlefields at Gallipoli, France, Palestine and New Guinea into the floors of the niches in the Hall of Memory in the form of the
