The building was restored in 1980, and in 1984 a new 20-story tower was cantilevered over it, bringing the total number of floors to 36. The tower appears to rest on the Cosden Building, but it is actually supported by an addition built onto the east side of the older structure. The entire project was designed to resemble the style of the Cosden Building as closely as possible, giving the impression of a unified whole even though the two sections of the building were constructed 66 years apart. It remains listed on the National Register of Historic Places under the same number that was issued before the conversion.
