This spot may be hard to find because it’s practically invisible among the trees in Northern Sweden. The mirrored walls of the glass box reflect its natural surroundings, acting as the perfect camouflage. Suspended 4-6 metres above ground around the trunk of a tree, the 4x4x4 metre box is made from plywood with a birch surface and you can look out of its six windows at the totally panoramic view of the forest. But don’t let its size fool you – it’s big enough for two people with a double bed, bathroom, living room and even a roof terrace. While it lacks ostentatious furnishings, it makes up for it with the unobstructed scenery of the tall pine forest and Lule River. Fun fact: the glass panes are laminated with a transparent ultraviolet colour which is only visible to birds and prevents them from colliding with the treehouse.
