No installing to the wall shelving unit
Books and papers cannot be left all over the house; we need a place to put them so they look nice and tidy. Again, cinder blocks provide a solution to this problem. Instead of buying a regular bookshelf, create one without leaving home or spending a lot of money.
For this project, grab at least four blocks and arrange them in pairs, two for each shelf. On top of each set of blocks, place a wooden board to form the surface to place and hold objects. You can design the shelf as tall as you want and adapt it to your space. The best thing is that you can modify it whenever necessary.
