Even if you don't have a room in your home to dedicate to an entire treehouse, there are some wonderful takeaway ideas that can be incorporated into a child's room. We love the tree sculpture that juts out into the space. And if you're handy, the stairway nook and slide could be replicated on a smaller scale, with storage built into the steps. (Slides similar to the yellow plastic one pictured here can be found at large home/hardware stores for around $100.) For more photos, be sure to visit Minor Details.
