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.

Pankaj, I just realized that initially you told us that the bathroom area was 12'-0" x 9'-0" and later you mentioned that it was 11'-8" x 8'-0". In the last floor plan, I forgot to change the bathroom with the new dimensions. Below is the floor plan with the correct dimensions for the bathroom. The bedroom is ok, I drew it 19'-2" x 12'-6". The new layout does not change the way things are placed. Everything still fit. The only difference is that the vanity is now 4'-4" long instead of 4'-8". and the toilet is closer to the shower by 1'-0". Can you give me the lengths of the walls K and L. They are the walls between the vanity and the shower area. I will send you the new layout once you give me the length of these 2 walls.

It's a bit hard to tell, it looks like some of the proportions are not correct. Given what you have drawn it looks like entering and exiting your shower is going to be awkward. I'm not certain that you'll be able to open the door all the way because of the placement of the tub and vanity. Here are a few suggestions: Ditch the corner tub, and use a rectangular one that is installed with the long end on the wall opposite the vanity and shower and install the toilet next to the tub. Slide the door to the right, and you'll be able to have a larger vanity and/or shower. If you can use a pocket door or something of the like you'll gain wall space like sandpat mentioned. I don't see any storage planned. Have you thought about where you'll keep towels, toiletries, etc-?
