....from a previous instagram posting (supraorder) - an office building in Heilbronn / Germany. the plan drawing and its elements are a great example for the way you should draw your building......stair, elevator, structure / structure grid, facade (glass with two lines and mullions), etc.

note that in germany you do not need two egress stairs....here you see one egress stair on the outside, and an open stair at the elevator core - in the united states the open stair at the elevator would be a “monumental” or “convenience” stair (and therefore can stay open and be connected to the elevator lobby). you would need a second enclosed stair somewhere inside or outside of the building for egress.
