Growing up, some of us had boring, normal houses on the ground. Some of us were luckier, with more inventive and industrious parents, who built us homes in the trees. No matter which camp you fall into, or which tree you fell out of, this collection is a sky-high look at some of the finest tree houses ever made. Whether it's a teahouse, a restaurant, or even a hotel, these homes take treehouses to the next level, and will make you even more jealous than before.
