This is less of a man cave and more of a mini castle. If you are able to put together a structure like this on your property, then you are going to have one cool spot to get off to by yourself. Not only that, but your friends will love hanging out in this cool space. In addition to being so awesome, you could also argue that something like this could significantly raise the value of your property. So really there is two pronged effect when putting something like this by your home. In any case, this is about the coolest man cave ever.
