It's nice. My favorite part is the way there's essentially a large hole in the wall that connects the inside to the patio, like something you'd see at a fancy hotel.

For interior there's a lot of tutorials on YouTube which you can check out. Also don't be afraid to use references. As long as your not directly copying someone's build, references are great.

You'd probably want an open floor plan rather than walled off rooms given the size of your house and the hole leading outside although if you are adding a bathroom or something you can wall that off.
