There's a new type of treehouse out there and it's taken the whole idea of arboreal living to a new level! These creations are just stunning combining ecological sympathies with natural, beautiful design. These images are from Nelson Treehouse and Supply in Seattle who have manufactured all these gorgeous designs. This treehouse is actually a tiny brew house complete with full production facilities. It has custom windows, a beautiful 'peacock' feature window and cathedral ceilings inside This multi-level design complete with bridge, rope escape and crow's nest is surely every child's dream! Now this is a serious treehouse. There are many permanent ground-hugging dwellings that are no match for this creation. Built as a backyard getaway, this design was inspired by the client's trip to Ireland. The circular theme lends itself to good traffic flow and sweeping lines. We love the central fireplace, cork walls and green roof.
