I like very much the idea for the office! Also the other one.

Should I leave the door for the office near the stairs, once entering the house, or should I remove it and leave only the access through the living room?
Imho I should leave the door .

For practicity, let the door if not you should do all the round to go to the entry.

In the same style, you can put a sliding glassed door between office and living room like this :
