Speaker setup for this room

Hi all

I am in the process of building a home and not sure about the best (if any) sound setup I should implement in my main living area.

I have attached my floor plan and some 3d images on the links below:

Link 2
Link 3


Basically there's an entrance (3m high ceiling) that leads into a living area on the right (6m high void) and another area on the left (3m high ceiling). The dashed line in the floor plan is just to show separation of the two areas (different heights), this isn't a wall, it's all open. I've also shown a section of what the TV wall looks like. I have to maintain min. 300mm clearance from the fire place.

Absolutely no idea what to do here, I know it's not an ideal room for sound, but any suggestions would be better than audio directly out of the TV. I need it to look aesthetically pleasing too, so placing floor standing speakers around the room isn't an option for us.

Love to hear your thoughts!
