He pointed out that Barnes' building has only one front entrance -- a large revolving glass door.
"If that circular door is broken, what happens? You need a plan for people like me, in a wheelchair, to go through. You need more than one door," the architect said.
Graves, 78, has been paralyzed from the chest down since a spinal infection in 2003. He continues to practice and travel.
During months of recovery and rehabilitation, Graves noticed many shortcomings and failings in the design of health care facilities. Since 2009, his design group has partnered with Stryker Corp., a global medical technology and equipment firm based in Kalamazoo, Mich., to develop designs to make health care settings more comfortable for patients.
Graves' true education as an architect began in 1960, when he studied in Italy for two years as winner of the Rome Prize. He spent most of his spare time in the American Academy's library teaching himself classical art and architecture, which influenced his entire subsequent career.
That experience in Italy was "a kind of homecoming," Graves told a packed auditorium during his public lecture Wednesday on campus.
