This game is about you, escaping as a scientist from Black Mesa Headquarter, A new building build in 1956. This building we're used to hold some public project. Before you joined as a scientist, you need to do a training on a Hazard Course. The Black Mesa Headquarter is much the same as Black Mesa Research Facility itself.
I really don't know.
I'd add a window and a wooden bench where you can interact with a security guard or maintenance worker behind it. Add some sort of office in there. Then the bench would also make more sense as some sort of waiting area.
An office similar to this:
Media.moddb.com
only open instead like seen in the Blue Shift Intro where that 1 scientist complains towards the Security Guard that he can't access his office and computer.
