Part of my hesitation was getting the time to stud, and drywall the room. I decided to just paint the concrete walls. It also gave me another precious foot of space. For the one wall between rooms that was already built using metal studs, and drywall on the storage room side I used a little creativity. On the gun room side I used Hardy Board concrete backer board. Then I filled the screw holes with concrete caulk, and added a few odd shaper dabs here and there. After painting it with the same light grey concrete paint I used on the other walls it blended in, and looks just like the other rough concrete basement walls.
I still need to put a couple outlets in. I have a couple circuits close that I dedicated to that room, and will use conduit, and surface mount outlets by each bench, and one in the area I can add another safe in.
