French architects Bruit du frigo have built a series of cylindrical shelters around Bordeaux. Placed amongst the trees, the ‘Tronc Creux’ are designed for hikers and outdoor adventurers.
The outdoor retreat is completely off the grid and its design resembles hollow logs to ensure the structures don’t impose on their natural surroundings. Nine people can spend a night for free in the forest inside a Tronc Creux, although there is no light or water in the unusual location. Bruit du frigo writes:
The original idea came up with the project of making a hiking path all around the city, connecting waste land, parks, forests and giving as such the possibility to anyone to make short holidays in its own neighborhood while exploring unknown areas.
The low-tech shelters are made from wood with a steel frame and the interior features three double and three single beds. Click through to see images of the Tronc Creux:
