the 56 feet (17 metres) to the north of the bank were in 1889 leased to one dunkerley for construction of a cooling chamber on what was actually described at the time as vacant ground. it appears that the construction of this was not proceeding satisfactorily and the company intervened to carry out the work. g.r. johnson was again commissioned and the new structure was given a façade harmonising with the existing building, though only one storey in height, and linked to them by a screen wall across in the front of a courtyard, now repurposed to the north melbourne entrance.
