Thanks Jami for the great resources.
I must admit I have a soft spot for treehouses.
I found this one today online, but there seems to be much more house than tree.
Not quite as stylish as the Miso house but its big & made of reclaimed materials!
Reclaimed Wood Tree House
Every bit of this treehouse is from reclaimed and recycled materials. Located in Crossville, Tennessee, it is 10 stories, 100 feet of height, 258,000 nails and built from a 80 Foot talk white oak tree.
Other recycled materials include, license plates, furniture, roofing materials, windows, skylights, bottles.
