[1] Designed by Melbourne architects A & K Henderson with assistance from local firm of Atkinson, Powell & Conrad, the contractor was G A Stronach, with the technical advice of Thomas Walker Pearce.

It was an example of the pervasive fashion for the neo-classical style in commercial and civic buildings, of similar scale and materials during the period.

Prominent features of the building included the large bronze doors in the Queen Street entrance, separate lifts for tenants, and a special women's banking section fitted with lounge, retiring room, writing facilities and telephone.

Over the years various professional tenants have occupied the upper floors - solicitors, doctors, accountants, architects, and optometrists.

The new head office was set up in the former Queensland National Bank building on the corner of Queen and Creek Streets.

[5][6] The National Australia Bank Central Branch, located at 180 Queen Street, is a seven storey structure with a steel frame and reinforced concrete floors and roof.

The three central bays are distinguished by flanking giant order pilasters which extend from above the ground floor level to the cornice line below the parapet.

[1] At the ground floor level the building has four engaged Doric columns above the granite plinth and flanking the three entrance doorways.

The second and third floors retain the original office layout and finishes, but other levels have been modified to accommodate larger tenancies.
