So, I think
- you should completely omit the windbreak (more of a one-person airlock). The hallway practically has no light with the windbreak! Besides, the hallway is already like a larger windbreak due to the existing doors.
- swap the study/guest room and the utility room; if the study is used more often, light (west) is not so bad :)
Besides, I would always try to separate my private rooms from the guest rooms. So guest on one side, bedroom on the other. You can also move the entrance further east, currently the path from the carport to the front door, or with groceries to the kitchen, is very long.
- no door from the bathroom (south) to the outside! Or is that supposed to be just a window?
- the size and location of the pantry in this form is not helpful. Better to put the pantry all the way to the left on the west wall with a direct passage in the middle of the kitchen where the stove is now drawn.
- at the bottom left (southwest corner) I would place a covered terrace, but bigger than in the drawing, at least 3 x 4 m. Accordingly, the furniture in the living room must then be arranged differently. Seating area to the right against the wall, etc.
