Worth watching
If you love houses, check out PBS' fascinating "10 Homes That Changed America," premiering April 5. The hourlong show highlights 10 influential homes that transformed residential living, from grand estates to the tenements of New York City. You'll discover what was influential about well-known homes, including Thomas Jefferson's Monticello and Frank Lloyd Wright's Fallingwater. You'll also learn about lesser-known transformational dwellings, such as the Langston Terrace in Washington, D.C., a 1930s public housing project designed by African-American architect Hilyard Robinson, who believed in the power of architecture to transform lives.
There's plenty of eye candy, including a lavish look at the Gamble House, the California retreat of the wealthy Gamble family, whose handcrafted details by architects Charles and Henry Greene helped inspire a bungalow boom.
If you've been to Chicago, you've probably noticed the round, scalloped high-rises of Marina City. But did you know that they were bankrolled by the janitors' union in 1962 in hopes of revitalizing the city's downtown at a time when the middle class was fleeing the city for suburbia?
The show concludes with a look at the Glidehouse designed in 2004 by and for architect Michelle Kaufmann. Compact, green, modern and prefab, it's inspired many other design professionals and homeowners to follow her lead.
