A new level hotel experience in Sweden...
"The Mirrorcube is an exciting hide-out among the trees, camouflaged by mirrored walls that reflect their surroundings. The dimensions are 4x4x4 metres. The base consists of an aluminum frame around the tree trunk and the walls are covered with reflective glass.
To prevent birds from flying into the mirrored walls, they have been clad with infrared film. The colour is invisible to humans, but visible to the birds.
The interior is made from plywood with a birch surface. The six windows provide a stunning panoramic view.  A 12-meter-long bridge leads up to the treeroom."
