At the North Carolina Museum of Art, the Associated Press got a glimpse of the behind-the-scenes designs making it possible to safely transfer invaluable pieces as part of an expansion that will cost $73.1 million in public money and $5.5 million in private funds. The work includes a tunnel and a hidden, roll-up door. The new building, designed by Thomas Phifer, has a "skin" that's about 50 percent glass, allowing in sunlight. Protective utraviolet filters, louvers and curtains are part of the design since art and light are usually mortal enemies.
