[1] Designed by Skidmore, Owings and Merrill, 3300 North Central Avenue was built in 1980.

[2] Oxford Properties was developer of the project, and Poole Construction was contractor.

It was built as the headquarters of United Bank of Arizona (later purchased by Citibank, then Norwest).

Like its next door neighbor, the Great American Tower, 3300 North is rotated 45 degrees from the street grid.

The building is covered with reflective glass with the exception of the corners, the crown and the lobby, which expose the concrete construction.
