What rooms would you deem necessary for a house, and how necessary are they?

I know for basic living for one single person and no pets, a bathroom, and kitchen+living room+bedroom are the bare essentials. So basically a studio.

What I'm looking for is some opinions on what separated rooms are needed/wanted for a house, and also how needed/wanted are they? I'd say the bathroom and "studio" room would rank as #1 and #2, unless you plan on having the "studio" area separate. In that case, these are ranked as:
Bathroom -1
Kitchen - 2
Bedroom - 3
Living room - 4

Maybe add in closets here and there, and a laundry room?

Bthrm closet - 5
Laundry - 6
Bdr closet - 7
Pantry - 8
Lvgrm closet - 9

But I know nothing of what rooms are necessary (or lesser known possible rooms/areas) for living, or even how big they should be. I know in my state, NC, the bare minimum is 720 sq ft, so shooting for slightly over that would be ideal for me. I don't want to have a huge house to clean, and I love cozy, small spaces. If I want to see some larger space, I'll look out a window or go outside.

So what would be your numbered list for priority rooms in a house?
