the best suggestion would be to contact a design professional or a cabinet company to assist you, as a project of this nature could take hours to design and refine and then the production time for the design needs to be over seen by a knowledgable person good luck....this is a for pay type of design issue

Given your space constraints, I think it would be best to hang the TV on the wall that is common to the study/living room (just to the right of the door entry). You could get two or three small upholstered chairs for the living area (gives you flexibility in moving them around.) I would have a table surface hung so it can swing out and be used on the wall between the door and the opening to the kitchen. If hung with a hinge attachment so it can be flat on the wall when not in use, you still have space to move around. Backless bar stools could be lined up on that wall when the table is stored flat to the wall, and still be used for more guest seating.

You will need space to walk and for your feet if you turn the chairs around - if you put a divider in you will block the view from the dining table out to the balcony - and thus make the kitchen and dining room both have no view ! So if you keep it open, the natural light can get through !

For the dining room, I think I'd orient the table 90 degrees from how it's drawn, and I would make it a drop leaf or gateleg table so that it can be made smaller when not being used for dining. I would embrace the idea that the entry is right in the middle of the living room, and bring the living room furniture out towards the fireplace so the fireplace is connected to the seating area. Maybe TV above fireplace. In that back corner where the sofa is drawn, I'd make that a small work/office space.
