Beautiful design. I'd want it higher in the tree and larger in diameter. Awesome though. Without spraying around the trunk, how would you keep the ants out?

Excellent, , , all of it!

@Buellrider , a thick wad of grease around the trunk just beneath the structure will take care of all crawling insects. What an awesome structure!!!!

Coffee grounds Buell, coffee grounds. Ants don't like it. Nor do they like blendered onion, garlic and any chili pepper and watered down. Either works, try it.

I think it is superb. I live on an island in The Philippines, on top of a ridge, some 20,000 square feet of relatively flat land, until recently a jungle. It took me 2 years to clear it, and this year we will build our home, a home with 3 outside walls, in a square building. Our guest house will have no walls whatsoever, but will be completely private. That should be done next year, given we have enough money left over. We don't like living in conventional housing.

Great idea !!!!! How can we arrange to come for a visit and we would also like to visit the structure going to be build in the phillippines by lonv166...feel free to email us...

What keeps the weight on the bottom and top of the house from stripping the bark and potentially killing the tree?

That is a really nice tree house. It is cool that it blends into the environment it is put into. :)

This looks like it would be a lot of fun for a few days.. It has been a long time since I slept in a tree house and ran to the main house to use the "Potty" or to have a 5 gallon bucket handy.. Is the Romance???

"What keeps the weight on the bottom and top of the house from stripping the bark and potentially killing the tree? "
There appear to be some brackets with bolts at the top, which seem to hold the treehouse up on the trunk. Not too keen on that idea. Why not have some wooden braces (complete with their bark, for aesthetic purposes) from the outer diameter of the shell fixed to a collar which sits on the ground around the base of the tree. That way there'd be absolutely no strain on the tree trunk, which would simply be used to stop the house tipping over, with the mass resting on the ground.
If you built some bearings in you could even rotate the treehouse about its central axis and have a different view every day. ;-D
