The German architectural bureau ‘Baumraum’ is a renowned expert in the design of amazing tree-houses. Most commonly the structure is made of wood and metal, and features such comfort and coziness that it doesn’t yield to the standard houses in any way. Of course the tree-house doesn’t have a kitchen, but it hosts a comfortable bedroom and a great reading nook. The lovely porch, built on a separate platform seems like the perfect place for sunbathing or for the morning coffee.
