I just figured it out: This person is from India (hence no bathtubs - these are wetrooms w/ shower only and a floor drain) and since this is a corner lot hemmed in by neighboring houses, OTS = Open To Sky... ...and that massive staircase probably goes up to the roof where they have their only outdoor space as well as space for hanging laundry, etc. IMO, putting the car on the exposed corner is the worst use of space and light - I'd stash the car on another side against the neighbor's house where there's no light - locating the public rooms and the kitchen along the front of the house and the bedrooms in the back where they don't necessarily need daylight - perhaps through the use of clerestory windows into the public rooms, the light can be borrowed for the center bedroom... Either way, Inkwitch is right (if a bit abrupt) I'd get a new architect who has some talent for efficient small space design to do your home.

Hello, and more storage is always great. I think if you could consider the height of your doors & trim and even the window height and trim the height of linen cabinet would relate nicely to that dimension. So I would measure a couple of those items and see which dimension is better in relationship to those elements in the room.

I really dislike corner tubs and as for whirlpools I find most are used for the first month and after that the time it takes to fill the tub and the amount of water wasted is an issue. If possible I would try to design the bathroom another way to avoid the corner tub design.

it will look small in proportion and chopped off in my opinion. why not a wet room shower? 3×7
