These should be in order of floor. The first is reception and behind the divider wall is Markiel's office. Second is everyone elses office. Third is Seph's office/home. Finally there is the roof. I haven't done the basement.
Now of course these are empty. I didn't want to clutter up the middle floor as I feel you all have a right to mess with your own space however you want. The first floor I'll be describing as best as I can in my first post. The bosses offices are of course private and as such I'll save them for when you get to visit them. Finally the roof is also free to be messed with. I suppose you could also add a small metal staircase between those two levels.
@Witch Cat Oh I wasn't going to ever do the fine detail with minecraft. I just wanted the building for general layout. At most I might put in the front desk because that is something rather built in, but otherwise yeah it's just there to be the walls and stairs.
