Leland Burns is a professor of Urban Planning at Cambridge and UCLA. His house, by architect Charles Moore, is imaginative, playful, colorful and memorable. It's a "harmonious and fruitful collaboration between architect and client." This is the third in a series, presented by Ted Wells, about four architects and four clients who were committed to the ideals of modern living. These clients are true patrons: generous with their praise, evangelical in their fervor to spread the spirit of Modernism, and satisfied that the rest of the world has finally caught up with their foresight. www.tedwells.com
