We had a tight odd space and needed space to store stuff. We went to container store and they helped us with a custom wardrobe that helped us with our needs. It costed only $250 for everything.

How to do this project
The space is odd because it's a door that comes from the garage and has another door to the house.
Mark the top bar holes and drill them. Make it sure the top bar is level.
This is extremely easy because all you have to do is to screw only this bar to the wall. The vertical hardware just attached to the top bar. Easy!
We love open storage because it makes it so much easier to find what you're looking for.
