Images of My Changes to the Shared Cloud Model
I added a second balcony off of the art gallery on the third floor, as you see on the 3D view above and on the floor plan below.
I also sectioned off and furnished a room on the first floor for private study / relaxation space, as you can see in the 3D view above and the floor plan view below.

I compared my version, #12, which version #3.

Description
On the first floor of the building, since there was an open space in the hallway, I thought it would be useful to section off a 400 SF room that can be used as a small quiet study area, as well as have something practical like a copier. On the third floor of the building, I thought it would be more visually pleasing from the exterior to have balconies on both sides of the buildings (there was only one on the left side from a change before me). I also thought that in a space like an art lounge it would be nice to be able to step outside, so I created a small hanging balcony with a couple of seating arrangements.
