I was watching a youtube video of someone playing a video game called Splinter Cell and saw this piece of dialogue.
"Hmm...work permits, architectural plans...interesting...Zherkezhi has a hardened panic room off of his bedroom."
a. At a certain distance in space or time: a mile off; a week off.(American Heritage® Dictionary of the English Language)
- located apart from: a village off the main road. (Random House Kernerman Webster's College Dictionary)
Does it mean it's not in his bedroom but somewhere near it?
