His focus on "liberating" architectural form was notable from an academic and theoretical standpoint but resulted in structures that were both badly built and hostile to users. The Wexner Center, hotly anticipated as the first major public deconstructivist building, has required extensive and expensive retrofitting because of elementary design flaws (such as incompetent material specifications, and fine art exhibition space exposed to direct sunlight). It was frequently repeated that the Wexner's colliding planes tended to make its users disoriented to the point of physical nausea; in 1997 researcher Michael Pollan tracked the source of this rumor back to Eisenman himself. In the words of Andrew Ballantyne, "By some scale of values, he was actually enhancing the reputation of his building by letting it be known that it was hostile to humanity."
