The offices in the picture(s) don't look very private to me, more like glass cubicles with the larger (but transparent) partitions.

Combined with people having their backs to (open, or in any case transparent) doors, this is very different from what I'd consider a "private" office.

If I were in charge of that place, I'd at least put semitransparent/frosted glass covering on the glass panels there so you can see if the room is occupied but can't peer behind someone's shoulder.

Also depends on the type of panel used, but such large surface glass panels are terrible at sound isolation...
