The Treehotel in Sweden expands its offerings with the Biosphere. Designed by Bjarke Ingels Group, the 365-square-foot dome is suspended in a Swedish forest and covered with 340 bird nests in an effort to help conserve the area's bird population. The interior is accessed by a rope bridge and features living spaces furnished with natural materials. Walls of glass give guests unique access to birdlife, while a rooftop terrace situated in the canopies affords panoramic views across the forest.
