Imagine a special little house, made out of cardboard. Cardboard doesn't seem like a suitable material for building. Yet, we have seen it done - Dutch design studio Fiction Factory is now offering a microhome constructed out of layered cardboard that they say will last up to 100 years. They called it Wikkelhouse ("wrapper house").

One 1.2-meter (47 inches) thick, 500-kilogram (1,100 pounds) module can be then combined with other modules to form a larger structure, without the need for a monolithic foundation. The modular design allows for scalability, a flexible layout and ease of customization and assembly. Once the initial structure is assembled, it's covered with a waterproofing material and finished with exterior wood panelling. After transporting the modules to the site, assembly only takes around one or two days to complete.

And this is not all - modules can be moved anywhere to be reused and are mostly recyclable. Just great, isn't it?
