Treehouses, although a staple of childhood, are really just as enjoyable at any age. In fact, the only people who don't like treehouses are soulless voids -- perhaps belonging to some underground race of evil, fun-hating mole-gnomes. Here are 39 awesome treehouses you wish you lived in (and a few pretty scary ones you'd probably never want to visit).

Treemansion.
A lonely farm treehouse.
A futuristic treehouse at Burning Man
That must be one rich kid.
There's not much tree in this treehouse.
Lonely like the other farm treehouse, but damn cold to boot.
A mosaic-fronted treehouse. They must be fans of modernism.
Yar! This treehouse has a crow's nest so you can spot...sealubbers...
Let's hope it doesn't flood.
The time-honored classic.
The not-so-classic.
The giant birdhouse.
A strange French treehouse Chapel.
A Japanese treehouse restaurant.
Lovely portico. Or is it a vestibule?
Bamboo, baby. Built to last.
A precariously placed treehouse.
Another old standard, but this time with a balcony for good measure. Ooh la la!
Built-in defenses.
Nice, but a drawbridge would have been even cooler.
Treetop hut.
Disneyland...is this cheating?
There isn't 'mushroom' inside this tiny treehouse. (Send complaints about the gaudiness of this pun to punanonymous@gmail.com)
Buried within the shaded branches of the tree. Tres romantique!
One of the few treehouses that's acutually inside the tree.

Tree-castle.
Screw the Navi'i: this is the real stuff.
Have a ball.
Hey! What happened to that drawbridge idea? Is no one listening?

This seems to be at least three different trees joined together, making this a threehouse.
The most expensive part was the spiral staircase.
It's lonely (and scary as hell) at the top.
How the hell do you access those double doors? Are they a clever anti-burglary device?
There is something mildly disconcerting about that trunk.
