I have a question regarding 505.2.1 (within IBC 2015).
This section states: The aggregate area of a mezzanine or mezzanines with a a room shall be not greater than one-thirds of the floor area of the room or space in which they are located. The enclosed portion of a room shall not e included in a determination of the floor area of the room in which the mezzanine is located. In the determining the allolwable mezzanine area, the area of the mezzanine shall not be included in the floor area of the room.
Specifically, I have 2 questions.
I've used images from he Canadian building code appendix (as the IBC didn't have images in the commentary) for reference.

For the first, If my overall floor area is 1000 sq ft (for example only), and my mezzanine is 100 sq ft, does the first part of this definition state that the open area of the room is 900 (because 1000-100 = 900)? If the area under the mezzanine had walls up to the mezzanine, does the 900 sq foot number change?
Second question. If In in my 1000 sq foot room containing a 100 sq ft mezzanine I want to build an enclosed office on the 1st floor, with a dust cap above, does my overall floor area shrink by the enclosed space? Does the answer matter if the walls to this enclosed space is full height or not (see second image)?
