15. Make Your Own Cabinet
There is no need for a professional closet to create a large, sturdy cabinet, especially DIY. Screw the wall and ceiling with a few bits, then take some plywood to form the top, bottom, and sides of the cabinets.
The best thing about this basic cabinet system is that you can customize it to best suit your needs in different ways. It can also become a great place to set up a television garage and entertainment center.
