By eliminating the spare bathroom off the kitchen and eliminiating the OTS (What is that?) you could place the Master Bath back-to back w/ the other bathroom - saving plumbing costs...
...and freeing up additional space for the Living room.

In addition, I'd reorient the kitchen so that it's back counter is along the back window wall, and eliminate the wall between it and the Living Room - and integrate the refrigerator into the space plan rather than standing in front of a window all alone.

i would definetly share bathrooms with bedroom 1 and 2 , no need for all those bathrroms...and then that gets you extra room and the fridge by the window has to be moved....seams a bit of a complicated layput what is on the second floor? can't read what room is behind the kitchen wall...is that a food storage next to the bathrrom or a laundry room? maybe with just one bathroom on the first floor you can expand the kitchen space , all the way to the back wall

where is the eating area? i'd remove the bathroom from behind the kitchen and open up for bigger kitchen and dining space.

what's OTS?
where's the fridge? (infront of the window floating around?)
where do you sit to eat?
why so many bathrooms? Why not have the rooms share a bathroom?
Where does the person in Bedroom 2 (under stairs since you have 2 bedroom 2's) go to wash themselves?
What's the second floor?

actually, where do ANY of them shower?
you're bathrooms all have a sink and a toilet but no tub or shower. Something's missing...

Move. This layout is untenable and was designed by either a 5 yr old child who never wants to take a bath, or an idiot! Where do the stairs go? Is this a condo? Forget the whole thing and move.

I'm not a fan of this layout either. The kitchen is way to small, and for entertaining, you've got no-where to sit, and people are going to cram the kitchen to try to get to the bathroom, at a party it'll be a nightmare.

What is an OTS? Anyway, its creating a funny little box area in bedroom 1 that will be awkward to fill, and the back-to-back bathroom ideas make way more sense.

To me, this floor is all about bedrooms, not living space, and you have a whole 2nd floor - how many more bedrooms are there up there? Unless you live in a part of the country where you can also live/eat outside, this layout makes no sense. And since there is no door that I can see, to get you into a back garden space, I'm assuming you don't live somewhere like that?

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.

is BEPSF is right, then there's a LOT of work to be done on this one.

If space is limited, then go to a spiral stair, especially if it's just for roof top access.

not to sound repetitive, but i'd definitly go to a common wall for the bathrooms, clearly even shared ones might be best... as shown, the person in room #2 under the stairs has to go through another room to use a shower. The thought of having a wet room/bathroom boggles my mind...

and yes, gut it, start over, find a new architect/designer... especially if this is supposed to be something that's being built from scratch...

Whether India, USA or Timbuktu, the layout is really bad. Inkwitch might be a tad blunt but certainly dead on. Toss this plan and get an architect with some talent. Or don't and regret it.
