Robert A. M. Stern said of the building, "Nothing like it had been built, and only rarely...had anything near its size been imagined in the vocabularies of either the first or second phase of the International style. PSFS is much more than a superb marriage of function and technological innovation within the constraints of a new vocabulary of form. It is a superbly crafted object, refined in its every detail...PSFS is that rarest of phenomena of our time, a working monument."
