The Bureau A Antoine Boulder Cabin is a compact, single-room unit designed for one or two occupants. It features a wood-burning stove, a fold-down cot, a window and a skylight. And that’s about it. This boulder cabin has two distinct values to weekend campers. First, it provides a rare kind of privacy by blending in with the surroundings. Second, it’s safe and secure when you’re away, as those who do actually discover the boulder cabin will have trouble even finding the lock. It’s a natural camouflage of sorts that gives it secrecy and security, a great option for the hermit that truly wants peace and quiet. The boulder cabin concept by Bureau A is a completed physical dwelling, actually in use by its developer. More could be ordered to spec, but as far as we know now it is a one-of-a-kind dwelling. From our perspective, it’d be right at home in the Treehotel in Sweden, and if it came sooner, we’d have included it in our list of the best Nature Architecture 2014. It’s an incredible little design, an unique take on cabin architecture by Bureau A.
