From a giant sandcastle and a farm that floats on the ocean, to the tallest single-family home on the planet, Charlie Luxton explores jaw-dropping homes, and examines why the people who live in them choose to escape the everyday world. The funny, heart-warming and insightful programme meets a Bible-obsessed Dutch entrepreneur, a group of scientists pretending they live on Mars, and a billionaire YouTube celebrity with his own zoo full of wild animals named after Versace, Gucci and Paris Hilton, revealing what it takes to live in a one-of-a-kind wonder.
