The Mirrorcube is owned by Treehotel as a way for people to live and connect with nature in Sweden. The Mirrorcube was constructed in 2010, and the architects behind this masterpiece were Tham, Videgard Bolle Tham, Martin Videgard. The project is important because of its unique structure and living space. "The Mirrorcube is an exciting hide-out among the trees, camouflaged by mirrored walls that reflect their surroundings. The dimensions are 4x4x4 meters. The base consists of an aluminum frame around the tree trunk and the walls are covered with reflective glass." I believe the most interesting part of the building is the structure of the mirror cube building. Based on the studio's ideology I believe the extensive living component in the Mirrorcube is unnecessary/irrelevant.
