Wikkelhouse is a unique and eco-friendly house and is nothing like you've ever seen. It is made almost entirely of cardboard (24 layers of cardboard to be exact). The cardboard is layered around a house mold that is light and can be moved easily. The cardboard is then wrapped in a weather-proof foil and wood. Although the house is relatively inexpensive at around $29,000, it is made to last up to a century! Check out this innovative house below! Would you live in a Wikkelhouse?
