Cardboard is usually thought of as disposable and temporary, but a design firm in Amsterdam uses the humble material to build houses that are supposed to last for 100 years.
It's called a Wikkelhouse, and it's the flagship creation of the whimsical firm, Fiction Factory.
Wikkelhouses aren't just made out of regular old cardboard. They're made by wrapping 24 layers of high-quality paperboard around a house-shaped frame. In fact, the Dutch verb "wikkelen" means "to wrap."
The layers are bonded together, and finally the whole thing is covered with a waterproof, breathable foil that provides protection from the elements.
A single segment of a Wikkelhouse is 54-square-feet large, and multiple pieces can be linked together to create a larger space.
