One Commerce Square is a 30-story skyscraper in Downtown Memphis which is locally referred to as the "iBank Tower". The building was formerly known as the NBC Building and the SunTrust Building, and is the fourth tallest building in Memphis, Tennessee. The building is located at the corner of Monroe Avenue and South Main Street.[1] It houses the headquarters of Southern Airways Express.[2]


Construction started in 1972 by the National Bank of Commerce (NBC), and the building was completed in 1973, preserving the original bank lobby that was built in 1929. One Commerce Square represents a modernism architectural style and is currently a Class A multi-tenant commercial office building in downtown Memphis. It was designed by local Memphis architect Roy Harrover who also designed the Memphis International Airport and Memphis College of Art. Locally, it became known as the "NBC Building." In 1984, NBC sold the building for $46.1 million. In 1996, the building was sold out of foreclosure for $21.7 million.[citation needed]

The building was purchased in 1999 for $31.5 million by Jacksonville, FL-based Southcoast Capital Group, which operated as One Commerce Square LLC.[3] However, One Commerce Square LLC defaulted on a $24.5 million loan dated December 20, 2002, through Archon Financial LP. In 2003, The deed was then assigned to Regency Savings Bank, which merged with Park National Bank.[citation needed]

In 2005, NBC, still the anchor tenant of the building at the time, was acquired by SunTrust Banks, and the building became known as the SunTrust Building. SunTrust, vacated 155,000 square feet (14,400 m2) in the building when its lease ended in January 2009.[citation needed]

The building suffered a major blow when its anchor tenant, SunTrust, vacated 155,000 square feet (14,400 m2) in the building when its lease ended in January 2009.[4]

On October 30, 2009, Park National Bank was taken over by the Federal Deposit Insurance Corporation and the bank's assets were sold to U.S. Bancorp.[5]

It is currently owned by a local investment group known as Memphis Commerce Square Partners, who purchased it from U.S. Bancorp in 2010, and managed by Cushman & Wakefield.[citation needed]

On October 8, 2010, regional airline Pinnacle Airlines Corp. announced that it intended to move over 600 employees that will occupy 155,000 square feet (14,400 m2) on 12 floors of One Commerce Square.[6] The move, which is slated to occur in the autumn of 2011, is contingent on a lease with the potential ownership group of Lynch-Schledwitz-Prosterman. They hired architecture firm Looney Ricks Kiss to design a makeover of the building. Pinnacle and the Lynch-Schledwitz-Prosterman group are also attempting to acquire tax and other incentives to land the deal.[7] Pinnacle Airlines announced in January 2013 that it was relocating to Minneapolis, thereby vacating the space mentioned above.

In June 2012, a branch of Memphis-based Independent Bank (or iBank) located one of its branches in the building. It also installed a neon version of its bright red “i” logo on the top of the building’s east and west facades.[citation needed]

In June 2014, the State of Tennessee became the fourth anchor tenant since the building’s construction. The State of Tennessee’s occupancy comprises ten departments of state government offices including the Attorney General’s Office, Department of General Services and Office of Information and Resources moving approximately 500 full-time employees to the building. To date, the current ownership has invested more than $10MM towards numerous building improvements and upgrades including renovations to the lobby, restrooms, elevator cabs/systems, mechanical systems, and parking garage.[citation needed] The building also recently completed an extensive building commissioning process to gain HVAC efficiency as part of its LEED submission.[citation needed] Other improvements include an upgrade to the parking garage elevators.[citation needed]

The former bank lobby is now an event venue known as The Columns. The Columns boasts 22 Ionic pillars, each 32-feet high.[citation needed]
