Treehouses are usually in trees, but this house in the lake is pretty darned amazing even if the only trees are hidden away in the bridge. The Treehouse Solling of Germany sits about 14 feet above the water's surface, offering a great view of the fish, critters and flowers of the forest.
Inside, a number of beds and benches make the site cozy, while ample storage makes it a practical place to stay and an impressive skylight makes for incredible stargazing even on chilly nights.
