The terms “self-sufficiency” and “off the grid” usually call to mind concrete fallout shelters or underground bunkers, but the efficient interior of this tiny home would not be out of place in a New York penthouse or San Francisco studio.
Austrian firm Wohnwagon has created five of these homes since starting the project in 2013. Using all natural materials, the company creates one-of-a-kind homes on wheels with a focus on sustainability and low environmental impact. Measuring only 269 square feet, each one comes with an expandable portion that gives you an extra 70 square feet when needed.
The exterior is larch wood, known for being durable, waterproof and sustainable. The interior is lined with spruce for a light, airy look. Sheep’s wool is used as insulation to regulate both temperature and humidity. The natural elements are not limited to the construction materials; the design is simple and naturally inspired.
The true beauty of the Wohnwagon comes out when you take it off the grid. Its 31-gallon water tank is refilled using an ingenious graywater system that pumps wastewater through a filtration system located on the roof. The process of cleaning and sanitizing the wastewater takes about 24 hours.
A wood-burning stove and solar panels ensure that hot water is always available, while a bio-toilet disposes of waste separately, turning it into liquid fertilizer for your garden. The rooftop solar panels can provide energy immediately or store small amounts for later use.
