What's it like to live on the edge? In each episode, viewers will meet homeowners who are living in/building unconventional homes in seemingly unlivable, extreme conditions: a house hanging off a cliff in an earthquake zone; a home shaped like a flying saucer that spins 360-degrees to rotate with the seasons; a house made entirely of living trees that grows over time... these are just some remarkable examples featured in this new series. Viewers will come along with the daring homeowners and extraordinary builders to find out first-hand what it's like to live in these mind-boggling homes... and via amazing 3-D animation, discover the secrets of how these home were built.
