1. the red area in the back on red is for the stair and you can put a door that can access that stair as an enter-exit point. Anywhere you like. You don't need to show the back left red part in your overview picture.
2. You can put privacy windows on the red walls, so it's not completely into the ground.
3. The front wall and every wall that is not red can have normal windows, also a door into the garden outside if you wish. Napoli is build on a hill, so the terrain of the villa is not flat.
4. Yes
5. You don't need to design a pantry for this kitchen, you can show an access to it. I guess is more like a cellar than a pantry, but is not a requirement.
To Jones:
Yes. it can be one or the other, but the front must face the garden. There must be two doors one is the access from the staircase, the other is where ever you see fit. The second door is not open, you don't need to make other walls.
To Bridelyn:
1. Partially, if you want you can put privacy windows on the upper part of the wall.
2. The red part is outside the ktchen, you just need a door to suggest this is the entry from the house. Anywhere you like on one of the two walls that surround the staircase.
3. Yes.
