I’m not sure what space you are talking about. This space outlined in red?

By the way, that armchair on the left is awkwardly placed.

That space looks more like foyer space than living space. Is that a TV behind the chair? Can you post a picture of the actual rooom, please

Is tah some banquette seating there ? If so the table is useless so I need more info and pictures please .

Is that a keeping room or is it your main family room? What did you mark behind the chair?

I've adjusted your plan and the red line is 8 x 10
