Floor plan change - Load-bearing walls in the apartment. What to do?

I want to renovate and refurbish an old apartment. However, I am unhappy with the floor plan. The walls between the kitchen and bedroom, as well as between the bedroom and living room, are load-bearing walls. Can they even be removed? The street runs along the bottom of the floor plan, and the garden area is at the top. Does anyone have tips for me? Somehow I can’t come to terms with just renovating the rooms.

Well, what can you say .. who is supposed to move in? What kind of rooms do you need? Which floor is the apartment on? How do the possibilities for water installations etc. look? Heating .. underfloor heating? Where do you enter the apartment? Is there a balcony/terrace? Where is the stairwell? Is there a basement room? Drying attic? and so on and so forth .. you see, you don’t just whip up such a project based on a floor plan.

Spontaneously under the condition that it is technically possible.

Would turn the pantry, toilet, and part of the hallway into a modern bathroom.
Office will then become bedroom.

Bedroom becomes office or whatever.

Bathroom becomes storage room.
Tear down the small room in the living room.

It is my parents' house. First of all, we want to move in as a couple. Also, I need an office. The apartment is on the ground floor.

There is no way around a structural engineer.

That will follow anyway. First of all, the question for me is whether I should take over the apartment or if nothing can be made out of it.
