Thread: Gun/strong room

Ok so after having a chat with a customer this morning and an interesting one at that hes and old guy that used to build the old bank and post office safes(hence a quirey about thermic lances that didnt go down to well with someone this morning) i kind of knew this was one of the many interesting things hes done in his life so asked him about how they were built i dont think i need anything quite as ww3 proof as one of these. Are there any rules/regulations on building a strong room for a cat firearms. Im thinking of doing it to my other house once we move into it. It has a concrete and block open basement so its a blank canvas. Cheers nd
