World's Weirdest Homes

Charlie explores a giant sandcastle, a farm that floats on the ocean, the world's tallest single-family home, and other one-of-a-kind wonders, and he meets some scientists who pretend they live on Mars.

Charlie explores an eco-friendly spaceship, a dystopian Disneyland, an underground cave home, and a monk who spent 57 years building his cathedral.

Charlie visits a kaleidoscopic house fit for a Canadian Batman, a Mexican house that floats on 160,000 plastic bottles, and a Hobbit cottage in Scotland, and meets their eccentric owners.
