If a tree house is a little too far, maybe take inspiration from Frank Lloyd Wright's buildings. To me they seem reminiscent of tree houses and the materials used always seem to blend in with the surroundings, then the architectural straight lines make a bold statement.
|Frank Lloyd Wright's 'Fallingwater'|
Tree houses can show you how to live within nature and how to incorporate natural and local materials into your home. Some thing as simple as the tree branch decoration can make a beautiful statement in the home without costing lots of money. (In my opinion the one below would look better if the lights were on a white cable, but sometimes they're hard to find)
Thank you for reading.
