This bivouac is inspired by the tree. The trunk and the shell the two main elements.
The trunk also houses the rainwater system and supply, as well as being a power generator, lighting system and stove. The iron branches support the wrapper and other structures, such as the floor furnishings, the modular bed, and the coverage of the roof top.
The living area has been equipped with fixed furniture integrated into the trunk. The sleeping area is located upstairs in an open space with the bed arranged along the perimeter. To suit a human body, the setting is human size, and of a trapezoidal form instead of rectangular. During the day, the sleeping area transforms into an observatory through the overturning of berths.
