Our most ambitious plans at this point are for the second floor. Here are a bunch of photos of it as it is now.
I also made this quick video, to give a better idea.

Our plan for now, subject to change of course, is to add a bathroom as follows:
Split small bedroom to make room for the bath
Arrange bathroom wall to avoid any window modification, eliminating the need to modify the siding
Bath will have a shower stall
Remove the French doors to the Master
Add a wall separating the landing bedroom from the stairs
Eliminate both triangle closets
Add closets roughly 36”x24” for both small rooms
Add a closet roughly 60”x24” for the master
