From humble mud bricks to an Italian mountain with the world’s most prized marble, we start with the foundations of the home. Explore the cave dwellings of our earliest ancestors and the wooden homes of Vikings, all the way to the soaring skyscrapers of modern metropolises. Some of the incredible locations on the itinerary include a sleek, earthen eco-retreat built of lava; an ambitious archeological effort in France to build a medieval castle from scratch; Hampton Court Palace to explore the history behind King Henry VIII’s brick pleasure palace; Pasadena, California, where movie buffs will recognize an iconic American Craftsman home; and San Francisco, where we meet award-winning designer Yves Béhar who is designing homes of the future.
