The unnamed one in the south is actually quite large and can be used as two rooms, one large and one small, and the smaller one can be used as a study. Then make a small bathroom at the entrance, otherwise what would you do if you wake up at night?
The unnamed one on the north side is the living room to the left of the toilet (it seems a bit small). There is space in front of the toilet door and the bedroom, where a dining table can be placed. If you mind, you can add a screen at the door of the toilet.
The bedroom is quite big, and I feel like I can use a small part of it as a kitchen.
The above is purely imaginary and does not depend on Feng Shui.
