A AV closet can be a handy addition to your home. It will get all of the unsightly components of a home entertainment system out of plain sight and in a single location. A media closet is an enclosed space where you can store your DVD or Blu-Ray player, CD changer, game consoles and much more. It can be a simple project to build a media closet, especially if you already have a small closet in the room where you wish to install one. All you’ll have to do is know how to build it out.
