The best and most secure place to have a safe installed is at the corner where a couple of outside walls meet. This will provide more support and protection for a large, heavy safe. In a house that has several floors, the safe should be stored and installed on the ground floor. Smaller handgun safes can easily be stored in the corner of a closet. Where the safe is stored and the best place for it will depend on the type and size of the safe and the layout of your home.
