All these notes are based on the second version of your plan. The second version of the master closet is really not much smaller in functional space than the first...the first plan has the entry incorporated into the closet plan, but it is not useful space. What I would consider is giving up two feet of space in the office, and creating a wall of storage between the closet and the office. I'd divide it into three sections... the two on the ends would belong to the closet, and you could build in shelving for shirts, shoes, sweaters, purses...all the things you don't hang up. The center section would belong to the office, and would provide a storage closet for that room, which I don't see on the current plan. Since that's the bearing wall of the house, you need load-bearing vertical supports in that wall anyway, so dividing it between the rooms would allow for that as well. You could include alcoves high in the wall for luggage. Your hanging clothes would run around the other two sides. Then you'd have room in the center for your packing counter. And in the master bath, if you make the laundry room wall into your linen storage, you can eliminate that linen closet, put the door to the john where the closet door is shown in the plan, rotate the shower 90 degrees and stretch it along the wall that now shows the entry to the john,stopping about 2 feet short of the end of the wall to keep the entryway wide enough. Its door would face the laundry room wall. Then you'd get your tub and your big shower, you'd have room just inside the new door to the john for a small hand sink, you'd have even more knee room and privacy in there, and you wouldn't have to go back into the bathroom to wash your hands.

My laundry is on the 2nd floor and it used to shake the house like crazy...it was a front loader. Just bought a top loader and now I don't even know it's on. So I would definitely go with a top loader.

Browse the office photos and see if there aren't ideas there for this space. Think about storage for homework accoutrements and games, maybe a conference-type table that can double for homework and games, something like this perhaps: There are 211,590 more office photos here: https://www.houzz.com/photos/home-office-ideas-phbr0-bp~t_732#viewAllPhotos

I see you’re not getting much response here so I’ll jump in. I feel that the gray/black vinyl floor trend is out of favor now, but obviously since you already have it (and like it) you should choose something to blend with those colors. Is there another option you might consider, besides more vinyl plank? A deep gray carpet maybe?
