The Tree Hotel consists of small cubic rooms as hideouts in a remote forest of Sweden. The walls are made of mirrored glass with an aluminum base, suspended 40 feet above the ground for 360-degree views of the forest. The unique structure beautifully reflects its surroundings, blending right into nature. To prevent bird-related accidents, it’s been coated with an infrared color invisible to humans.
