I am building a new house that is focused around sustainability and living off of the grid. One of the main designs to be incorporated in the house is a safe room to be placed in the basement. All walls will be constructed of poured concrete with chicken wire placed inside of the concrete forms to prevent breaching. I have plenty of available space for the room. Ideally, it will be around 20x20.

I'm looking for pics of already constructed rooms or ideas from others that have been planning their own. The room will serve a double duty as my arms room and storage area for sensitive items and a supply of emergency rations to last a month or so until I can gain access to my stockpiled caches around the property...
