There’s an old saying that a man’s home is his castle. Truth be told, it really isn’t. If you’re a married man, it means you share your home with your wife, and most likely your kids. That means you can’t hang your posters in the living room, which is probably overrun with children’s toys. You may no longer have privacy in your home, so why not gain your own space with a man cave in your backyard? You can convert a portable garage, shed, or other outdoor storage building into your own backyard getaway. All it takes to build a backyard man cave is some creativity and ingenuity. Once you assemble it, your backyard man cave can be the home-away-from-home you’ve always dreamed of.
