Since its inception the building has generated much controversy. The coronation frontal view Chippendale style was too “kitsch”, the entrance was criticized for providing little protection from the weather and make the visitor feel small, and Johnson was charged with possession of an architectural style pioneered by others.

The corporate offices of AT & T in New York City, then Sony was building at the time of its design and construction to design a striking departure “glass box” of many office buildings tall at that time. The binding of an innovative steel structural system, a series of architectural requirements and a challenging for the project in the center of Manhattan engineering resulted in what the architect Philip Johnson calls his “….capolavoro…. the culmination of my life’s work…. ”
To make revistieran 197,5m tall building with a monumental presence at first glance, Johnson crowned him with a single post-modernist curved like the completion of a drawer style “Chippendale”. Like his work in the Seagram building by Mies, international style, this building was a model for a new style to be followed by other architects.
Carter Wiseman critic described the building as “a fusion of aesthetics and corporate trading rebellion logo… more architecture, more artistic ornament termination”.
It is striking that were Philip Johnson who created this project, the same Johnson who in 1932 introduced in the United States or the international style was responsible for pure modernist forms and the Glass House at Connecticut. Philip Johnson completed this building in it year that PPG Place in Pittsburgh, Pennsylvania, a remarkably different but logically like postmodernist approach.

For possible modifications were inevitable in the original design originally scheduled to host 600 people instead of the 1,600 that Sony raised.
On the street level, there were open under the building galleries created by the high columns of the base and behind the building, a gallery of 20 m in height through the block with a curved skylight. All these spaces had a mosaic floor of granite with a zig-zag pattern in the square gallery and other spaces.
