In 1957, Qantas House was completed to the northwest of the junction, with a curved frontage conforming to the planned plaza, named "Chifley Square".

However, in 1962, the Commonwealth Centre, owned by the Australian federal government, was completed on the site of today's Chifley Tower complex, and did not align with the planned plaza.

The southwestern corner of the plot became a pedestrian plaza, with a giant, two-dimensional sculpture of Ben Chifley, after whom the square is named.

[1] Due to its prominent location at the peak in the north-east CBD, the Tower has broad harbour views from its 42 storeys.

Current tenants include UBS, Blackrock, Servcorp,[5] Hana Financial Group and Bank of Queensland.

The entrance foyer for the retail arcades is located on the southwestern corner of the building, facing Chifley Square.
