It sounds like you are looking for a ready-made unit. You'll want to take measurements carefully including any doorways you want to get through. Ultimately, when you get it where it will sit el permanente, BOLT it to the floor. I don't think any yahoo burgler will take the time to defeat that precaution. Also, you might want to re-construct door ways to make it that much more difficult to get the thing out. I did that sort of inadvertently by buying a safe that would not fit through one door that it had to go through. No problem, I ripped the door frame off; put the safe where it was going, then rebuilt the door frame. I think that was a pretty good solution until it's time to move it down the road.
