First, I painted the wall a contrasting yellow. Than I got to work on the self.
Draw/ or any premade squares
dry wall screws/ wood screws (evaluate your needs)
bracket ( depending on wall) This wall had an off center beam so I secured it twice.
I see a clear work bench soon!
Step 1: Drawer
Step 2: Bracing and Hanging
You will be placing brackets on back bottom of drawer or place pilot holes in bottom of drawer to attach piece directly to wall. All this depends on your wall and what will be on the shelf. Please ask a professional to be sure the shelf is sturdy. I have a photo of tools to help.
You can use any combination for drawers I like these because the wood work is very nice it is worth salvaging because it is real wood.
You can stack the pieces in any direction, horizontal or vertical. They can also be stacked on top of another shelf or on a table. This oreintaion worked for me.
I placed two drawers one on top of the other. The drawers are screwed into the wall and I used brakets to give extra stability frim underneath. I needed to use plaster screws because the beam was off center.
Please consult a pro to decide how to place on you wal. I alsl have a photo of a shelf paced on another shelf to give more storage on top. This could be placed on a table to as well.
