Closet offices are great because they stay out of your way and still provide you with a nice, organised workspace. The main disadvantage, obviously, is that you're restricted to the size of your closet. Today's featured workspace is a great compromise because an office in a walk-in closet is really the best of both worlds.
Of course, not everyone has a walk-in or large closet in their apartment to turn into their next workspace, but if you do it's worth considering as an option. It's nice to be able to just shut the doors on your workspace when work is over and reclaim your home for fun.
