Pete Nelson Takes a look at some of the best tree houses that he has come across

Just one day of Christmas cheer isn’t enough for a real-life Santa and Mrs. Claus, who celebrate the season 365 days a year in Southern California. Old St. Nick and the missus call on Pete and his crew to spruce up their yard with some holiday magic. Pete creates a treehouse workshop complete with Santa's red chair, a naughty-or-nice drawbridge, a secret elf trap door, a candy cane and holly access bridge and some miracle Christmas snow...in the California desert!

Treehouse expert and visionary Pete Nelson explores the evolution of treehouses through delving into the many shapes and vast variety of functions they've served throughout the years. “Ultimate Treehouses 2” features a Papua, New Guinea, high-in-the-sky tribal treehouse built by hand, the world’s oldest backyard treehouse (more than 200 years old), a luxury treehouse gem in New York and a re-purposed airplane fuselage in Costa Rica. The special also spotlights fully suspended biospheres in the wild skies of British Columbia. Follow Pete’s jaw-dropping journey into the past, present and future of treehouse design.

Truly a worldwide phenomenon, treehouses extend to even the farthest corners of our world. Pete travels to Japan to tour with the country’s most beloved, renowned treehouse builder: Takashi Kobayashi. Longtime friend of Pete’s and truly an inspiration to treehouse builders everywhere, Taka takes his American buddy on a whirlwind tour of his greatest creations, including a treehouse bar in the middle of Tokyo, a luxurious spa retreat in the countryside and a touching treetop tribute to children affected by the devastating 2011 tsunami. All the while, Pete experiences the wonders of Japan’s wilds, the quirky excitement of Tokyo, and shares with us traditional Japanese experiences.
