A Place to Live

In this episode, Dallas explores how we have been redesigning the planet as we build ever more astonishing places to live. In Dubai, he climbs to the very top of the world's tallest building - over half a mile above the desert sand - to help clean the highest windows in the world; and he explores how desert wastelands have been transformed into bristling forests of skyscrapers as we've conquered the sky and turned it into a place we can call home.
