This is a Borneo tree house found on a post by the famous photographer
George Steinmetz. From his website:
The Korowai and Kombai live in tree houses that stand in clearings they have carved out of the forest. Beyond the pacification line we found people without clothing, metal, or any form of cooking vessel. This reality was made clear by the stumps of trees we saw there that had been felled (litteraly beatted to death) with stone axes, and resmbled giant shaving brushes. Although slowly dying out, there was still cannibalism in the area. Gerrit believed it to be part of their criminal justice system, as most of the tree-dwelers did not believe in natural death. The Korowai believed that most deaths were caused by sorcery, and they would try to find out who the sorcerer was to kill and eat them.

From
Freshome: "‘Free Spirit Spheres’ and are designed by Tom Chudleigh, and is an eco-friendly living quarter that was created to co-exist unobtrusively with its forest environment."
Again from the
Freshome Tree House post: "Takashi Kobayashi, one of japan’s leading treehouse creators. This house was designed after an advertising agency in Tokyo, hired him to design a treehouse for a Nescafé commercial now running on Japanese television."
Again from the
Top 8 Tree House post: "German cooperative Baumraum knows how to keep imagination alive in their homes. They create treetop dwellings which integrate beautifully into their forested surroundings, and preserve the integrity of the trees that support them"
Heres one from
the top 8 Tree Houses that I have included here: "Dustin Feider had a different vision: one that would be good for the tree, the environment and the deep human need to reconnect with nature and our primordial roots"
Nested 30 feet (10 M) above the ground in the canopy of a native Manuka grove, each Tree House has spectacular views of Kaikoura's dramatic mountains and surf-washed Pacific coastline. Check out this New Zealand Treehouse:

I found a superb article in
Popular Mechanics of how to build an
extreme treehouse. From the site
Any kid in Bridgton, Maine, would want to have Peter Lewis's playhouse in his backyard. And no wonder. Lewis has tricked it out with a drawbridge and two spiral staircases. Best of all, the whole thing floats 21 ft. off the ground.This one has me pretty giddy, click on the image below to see!
Here's another cool tree from the travel company
Across Indonesia. From the website:
Explore the lowland-swampy tropical rain forest in middle-south part of Papua Irian to meet the most unique tribes who live in the tree houses around 6 to 25 meter from the ground (some can reach heights up to 50 meters!), the Korowai Tribes.
From CookedBrains.net:
Okinawa's Treehouse Restaurant. It's actually an unusual tree house restaurant. "It's situated up in what appears to be a tree, but it's not a tree, just a very realistic rendition made of concrete. There's an elevator in the trunk that takes the customers up to the restaurant."
Horace Burgess treehouse church. Wow.
From USA Today:
The treehouse built by Horace Burgess rises 97 feet into the sky, the support provided by a live, 80-foot-tall white oak 12 feet in diameter at its base. Six other trees brace the tower-like fortress, but Burgess says its foundation is in God.

Here is one from
Joanna's Food Blog: In the autumn, we had a visit from a planning official, who said that there had been a complaint, and that we needed planning permission for "the building"..... Happily, the planners unreservedly took our side, and we did not have to demolish the treehouse.
Thanks to a comment in my blog from

If you are 'stumped' about where to build your tree, take a cue from Kevin McKinney! Also the original source of the tree house is down, so if you know its general location, leave a comment :) This picture is from Shardul.co.nz:

Linda Aldredge’s Treehouse - a lesson in sustainability. Read this great article about her tree house in New York (click image below) Quick quote
This is a house I simply can’t afford to keep up. I can’t afford to heat it in winter, which most cabins have to be in upstate otherwise you’ll have burst pipes, etc. I can’t afford a mortgage. I can’t afford water and septic costs. I can’t afford property taxes. It had to be sustainable. Just the very nature of my life forces me to choose this option.
Pete Wilson has built some marvelous Tree Houses. Check out his workmanship here:
