My grandfather had stealth storage everywhere in his house: above and between closet doors, in walls, etc. Wouldn't use in the same way, but always good for some secure storage

Secret/Safe Room - Great hiding place for home security for family in case an intruder enters your home. #homesecurity --- I love that only one would open so that even if they did catch on, they would have a one in three chance of getting it wrong and while they were going to the wrong door I would go to another hiding place.
