Norwegian architecture and design firm, Gartnerfuglen Arkitekter, harnessed the power of ice for their Unavailability Mobile Ice Fishing Hut, a clever shelter-for-one wherever subzero temperatures and water are at hand. It is a simple wood frame covered in chicken wire, to which water is applied—presto, instant ice walls, the igloo principle, updated. The one curious aspect of this collapsible hut: it seems to take two people to erect, but only seats one. A bit of a puzzle, that, but otherwise, very cool if you like the idea of sitting out in the frozen wilderness, which many do! And you can probably figure out how to put it up all by yourself.
