Mountain Lion

I already posted about the GREAT MOUNT.
Looks like you built a Gun Room with the Vault Door. What do you have for inside walls?
Thanks

I noticed that as well. Likely never build a new home again but already have plans for a built in gun room. Walls are 8” slush filled CMU blocks with 8” poured concrete ceiling. About all of the fire rating one can build in a residential building at a reasonable cost. Walls and ceiling will be rated higher than anything other than a true vault door.
