Convert a closet? It's on my list of todo's to frame out a secure closet in the unfinished area my basement. I was thinking of making an out swing Murphy-style door, but will probably just end up making a flush-fit door and hinges similar to a safe door. Which reminds me - why are the vault doors sooooo expensive? $1749 on sale for the smallest ones? For half that price you could get a safe, cut the front off of it and bolt it into a door frame.
