Capitol House (1924) by Walter Burley Griffin and Marion Mahoney Griffin sandwiched between them.
The brown building in the background is Barlow's Manchester Unity (1932) which echoes the style of the Raymond Hood's Chicago Tribune Building (1922).
But the white building in the foreground, Century House (1938-40), also by Marcus Barlow when compared to the Manchester Unity shows how much his thinking changed over the course of 5 or 6 years.
While both buildings have similar structure, each with a tower on the corner, the Century Building is much simpler and shining white.
The angle also shows the vertical columns that run the height of the building.
