This unique tree house was designed by German firm Baumraum, a company that specializes in planning and developing tree houses, either built on the ground or on water. This particular one is called the King of the Frogs that stands above a reflecting pond in a small private garden in Münster, Germany. Constructed with four steel columns, the interior of the tree house is attractively designed with a curved glass surface, gable roof and light flooding through the elongated windows. The most eye-catching part of the luxurious home is a large ceiling window, which enables children to peer up in the sky and observe the stars at night. The tree house offers enough storage space for books, games or blankets. A spacious deck area makes the perfect spot for playing.
