When Phoenix Corporate Center was originally built, all north and south facing windows had balconies.

In 1990, San Francisco-based development firm The Krausz Companies, Inc. purchased what was then called "Prudential Plaza," and undertook an ambitious repositioning of the near-vacant office tower.

Balconies were removed, and glass was reinstalled flush with the slab edge, substantially expanding the leasable interior space on each floor.

Additionally, several vertical columns on the north and south facades were removed, giving the building a smoother more modern appearance.

Colony has made significant upgrades to the property, including: renovating the lobby, painting the exterior, and building a marketing center.
