Terrazzo offered historically appropriate flooring material with low VOC emission and low life cycle costs for this 158,000 square foot, 100-year-old structure. Terrazzo was manipulated like oils on a large canvas to produce an artistic rendering with over 70 colors and 30 different aggregates. Floor murals blend abstraction, realism, and varied perspectives, depicting a butterfly with a 66-foot wing perched on an iris, a railroad wheel, a series of stars, a bouquet of daisies, and a pair of comedy and tragedy masks. Nine shades of yellow with three different aggregates, hand-blended on-site, show a microscopic view of a butterfly wing.
