Well, I've searched the forum pretty extensively and have either used the wrong search terms or have overlooked the specific thread. My google fu also reveals only a few hits that are relevant. Here's the deal. My collection is around 105 guns (haven't done a count recently). None are "collector grade" e.g., $5000+ guns, however, a very high percentage are $1000-2000 guns or historical firearms. Today, I have a couple of small safes that the higher value firearms sit in and the lower value ones are on wall racks. These all exist in a locked basement room with dehumidifiers. I want a secure, fireproof solution. I've looked into the really large (e.g., 60-75 capacity) gun safes. The biggest issues are 1) that the guns are really packed in there and tend to get "dinged" when I get them out 2) these safes are HEAVY and difficult to move...especially since I need to have them in the basement. Lots of twists and turns to get them there. So, I'm seriously considering a walk in vault. A few companies will custom build them (such as http://www.rhinovault.com/index.html ). I'm also looking into having a mason build one using rebar reinforced, concrete filled cinder block. Climate controlled and lighted. Fireproof vault door. I'm thinking a room roughly 6x8 or 8x10 would work well. Now the question -- where to find plans? Does anyone know someone that is qualified to design rooms like this? Are there plans available that can be purchased? Info is appreciated.
