The corner site was bought by surveyor and real estate agent Enoch Bostock who constructed an office which opened for business on 1 January 1878.

A three-stall stables was built behind the office and blacksmith William Hayne operated from there, using an entry in East Street.

Bank records show that "general improvements" were made in 1935; this is believed to have been when the pediment was built above the entry and the windows and doors were changed.

A modern single storey extension was made along the East Street frontage in the late 1970s, consisting of four individual tenancies.

[1] The former Queensland National Bank is a simple single-storey rendered brick building with a corrugated galvanised iron roof behind a raised parapet.

The symmetrical main facade facing Brisbane St has a central doorway with a modern glass door, surmounted by a pediment and flanked by a pair of rectangular openings which still contain early double- hung timber windows.
