I built this closet system for our basement gym as a Christmas present to my boyfriend. He loved it!
I stained all of the boards before building as suggested in the plan - it definitely saved a lot of time and stress. After cutting and staining, and I brought all of the pieces downstairs to build.
The actual building went relatively quickly, but without perfectly straight boards, the shelves themselves were a little tricky. I also just nailed the shelf boards down with wood glue rather than screwing them in to save time - it's still sturdy and secure.
The length of the closet is about 8 feet long, so the middle shelf is about 1 foot and the two rod shelves are about 3.5 feet long.
