Thread: Safe room specifications/designs

The term you're looking for is a "room of stout construction" for a reinforced plywood lined room, this is what a lot of Police temp armouries are constructed to. More info in the Police storage guidelines, or now FSA hosting the same document.

A "strong room" or "safe room" is the reinforced cinder block version...

Now, the biggest headache is your penetrations into the room (door, windows) and once you have those designs sorted the walls are fairly easy to tidy up. The storage guidelines document gives details of what would be acceptable.

If you PM me, I have done something similar and I can give you the details of what I did.
