Living in small apartment, I needed to maximize the storage space in my closets but being a renter, I didn't want to make any permanent changes. So I came up with this easy way of adding an extra shelf to take advantage of all the vertical space in my closets.
Step 1: Cut the mdf
I used 3/4" mdf and had it cut at the hardware store
Step 2: Attach the side supports to the closet walls
Since I'm a renter, I didn't want to use screws so instead I used repositionable adhesive sheets - they are strong enough to hold the pieces upright yet they can be removed easily without damaging the wall.
Step 3: Add top shelf
Place the shelf on top of the supports, and you’re done! This was one of the easiest projects I've done and I love having that extra shelf. I think I'll be doing this to all my closets in the future!
