When it comes to ingenious small-space design, there are loads of options that allow city dwellers to maximize space in necessarily compact apartments. But tiny living isn't just for the world's urban denizens; it's an eco-conscious way to live at all scales, in all types of environments. The Wohnwagon, a caravan produced by Austrian manufacturers, is a solution for the adventuresome lovers of small-space design among us—those who'd rather take their near-ascetic affection for living minimally on the road. The caravan comes in three sizes, starting at just 174 square feet and is designed for use entirely off-grid. It self sustains via rooftop solar panels and collects and uses rainwater. It also features a composting toilet.
