This article features an interior office space designed by Nothing, an Amsterdam based design firm.  The interior structures of the office are constructed entirely out of cardboard, an inexpensive and recyclable material.  The firm utilizes a “no screw- no glue” construction technique which promotes a cleaner indoor air environment as well as makes for easy replacement of one component if a piece gets damaged.
