Who knew people living in cardboard boxes could have the best pad in town? All it takes is a little ingenuity and some inspiration from the folks at Amsterdam's Nothing ad agency.

Instead of using traditional materials, the powers-that-be commissioned local designers Alrik Koudenburg and Joost van Bleiswijk to build them an office made entirely out of cardboard. As you can see, the results are pretty spectacular. To make things even more interesting, visitors are encouraged to decorate the cardboard with anything they choose. So, presumably, Nothing's walls will soon be riddled with penises and "for a good time call" phone numbers. [Nothing via CR Blog via Fast Company]
