The Wohnwagen Is An Environmentally Friendly And Self-contained Housing Unit, Designed And Created Out

The Wohnwagen is an environmentally friendly and self-contained housing unit, designed and created out of Austria. Each trailer provides 269 square feet of living space and their own off-grid electricity, water and waste systems. A green roof provides additional insulation, but features marsh plants that naturally filter greywater run-off from the sink and shower. The greywater is pumped up to the roof and is purified naturally over the course of about 24 hours, after which it is reused for showers or washing. The Wohnwagon also has a bio-toilet that separates liquid and solid waste before turning each into fertilizer.
