Cool Bookshelf Ideas: DIY bookshelves from recycled

 1- Wooden Ladder :

     Have an old wooden ladder in that shed that's no longer being put to use? You could
have yourself a free bookshelf with just a few nails and hammer. Flipping the ladder on it's side, it acts as a horizontal shelf, whereby the two side poles support the books, and the rungs act as built in book ends. The older the wood, the better. This will surely transform any room into a vintage-classic space.

2- Piano :
     While most of us don't have unused and unwanted pianos just sitting around, these can make neat bookshelves when tilted to one side and hollowed out. Just add a few wooden shelves of your own and you've got yourself a decent sized shelving unit that will be the focal point of any room.
