The lack of a sturdy tree in the backyard doesn't necessarily mean the end of your treehouse dreams. Check out the beautiful modern INDOOR treehouse created by Jennifer of Minor Details for a client.We love the "tree" she fashioned and the indoor swing. From the photo you can see a glimpse of the house itself. She shows another photo on her site. We're still living outdoors as much as possible but we'd love to have such a fun indoor structure once the cold and rain sets in.
