Bjarke Ingels Group, also known as BIG, is certainly the most cutting-edge architecture firm nowadays. We have already praised several of their projects, like the Audemars Piguet museum and hotel (Le Brassus, Switzerland), yet we cannot restrain ourselves from sharing their latest masterpiece, the hotel room Biosphere. This room is the newest addition to the TreeHotel, also located in Switzerland, and the last proof of BIG’s ingenuity. Biosphere is no less than a 34m2 spherical space made of glass, suspended a few meters above the ground, in the middle of the forest, and wrapped in more than 350 bird boxes! For the owners, who called on the services of a renowned ornithologist, it was essential that guests could get to experience the local biosphere from the inside of their rooms. Another remarkable feature of the TreeHotel is that each of its eight suspended rooms has been designed by a different firm. This last BIG project is due to be completed in the spring, but we just couldn’t resist telling you about it first.
