The steel-frame U-shaped office building is clad in limestone.

It was built by the Standard Oil Company at a time when that business was once one of the nation's principal corporations, the dominant supplier of gasoline and fuels.

[2] Standard Oil Building was listed on the National Register of Historic Places in 2000.

Following an extensive, $25 million renovation, the building reopened as residential apartments in 2002 by the Southern Management Corporation.
