This is the third tallest skyscraper in Rochester, standing at 392 feet (119 m).
It has 27 floors and was constructed in 1973. The building is unique for its
outstanding white vertical fins and the fact that it curves outward on the bottom.
The structure of the tower is a "tube in tube" design. The concrete core in the
center of the building teams with the stiff floor plates and the load-bearing
exterior tube of 24 tapering steel columns to provide an iconic silhouette on
the skyline as well as very flexible interior space. Twenty Four "non-functioning"
external columns are hollow and carry the utilites throughout the building. This
structural design results in a column-free interior.
