Nice thread but I have to say I've seen them all. Does anyone have any projects out there? I would like to think that someone would share something they were doing or a part of one, even if its not finished. Don't mean to seem rash, like I said, I like the thread.
Well it is not particularly green nor particularly unusual, but here is the tree house that I built in our backyard. I don't have any decent photos of it but here are a few that I took during an ice storm:
I'll try to get some better photos and add them to this post.
The house is 8'x8' and sits on a 10'x10' platform. The extra 2' perimeter on two sides is covered with decking boards. You get up to it by climbing a rope ladder with wooden rungs. Or you can just walk up the trunk of the tree.
I have a lot of materials (straw bales & lumber) stored under the house right now so it looks ugly underneath. Those will all be gone by fall. Also I haven't finished weaving the rope to put under the railing (although the kids prefer it without the rope, so they can sit on the decking with their legs hanging off).
You may have noticed the large horizontal tree trunk in the first photo. This is a large old english walnut tree (probably 75+ years old) which fell over during an ice storm. The uphill root broke. I figured the tree had been killed, so I was making plans for cutting up the tree, but in the spring it came back to life, and has continued to grow well ever since it fell over about 10 years ago. A horizontal tree makes an awesome play structure for the kids, so they were always up there playing on it. We got the idea to build a tree house in it, so I sized & shaped the design around the tree branches, and started scavenging materials. One of the posts is the top half of an old power pole that I salvaged from a ditch (power company accidentally left it behind). One of the beams is a piece of structural aluminum that I salvaged from another project. The windows are from our house, when I replaced aluminum windows with vinyl. The decking is left over Trex decking from a deck project. The shake roof and half the shake siding is made from shakes that I split myself, from cedar bolts I collected when I was a kid, and also old shakes removed from my parents roof when they had theirs replaced. I fabricated the door from cedar fence boards (the door is kid-sized). The house is covered in Tyvek that I found along the roadside (a remnant had fallen off a truck). The rope ladder is made from beachcombed rope. I did of course have to buy some lumber, plus all the fasteners.
One corner of the house was originally supported by the tree trunk, but I did not think about the fact that as the tree continues to grow, the weight of growing branches causes the trunk to drop. Thus after a few years the trunk was about 8" below the corner of the house that it was originally supporting (obviously the remaining posts held the house up fine). However it was a little wobbly so I added a couple of posts and more bracing. I still plan to add a few cables to brace it further.
Here is a view of one of the walls of shakes I split myself:
I put an electrical outlet inside with an extension cord plug outside, so I can run an extension cord up there sometimes. I hung an old string of icicle Christmas lights inside so the kids can play out there at night or have sleepovers, etc.
In the spring & summer you cannot even see the house until you are right underneath it, because it is surrounded by tree branches - you really feel like you are "inside" the tree. When we hired the permie landscape designer to do a design for the backyard, I offered to set up a table & chair in the tree house so she could work from there, and she did! You can see the whole backyard from there when the leaves are off. Here is a photo of my apple tree guild, taken from the tree house when the leaves are just starting to sprout:
I have some mason bee tubes hanging under the eave of the tree house:

In that shot you can see how I made a jog in the wall to go around the big branch in the foreground.
I built the walls & roof in the garage, then took it apart and put it back together up on the platform. At first I was super careful climbing around on the tree, but after a while you start to feel like
spiderman and can jump around in the tree with ease.
On one windy day I did some audio recording up at the treehouse:

Anyway, this was a really fun project that didn't cost much due to all the scavenging I was able to do. As I said I'll try to get some better photos and add them here.
