Not Tom design studio just scored a new fan with this one. The Book Book Shelf is not only a practical piece of furniture—if you choose to put something on top of it—it’ll also double as a piece of art by not putting anything on top of it at all. And it’s environmentally friendly.

Here’s a statement about the shelf from Not Tom: The idea for the Book Book Shelf came from the realization of how many books are discarded on a regular basis. These particular books were to be thrown out at the end of a jumble sale and we wondered what more could be made of them. We like the idea that value can be added to many discarded items through ingenuity and redefinition of context.
