Your sitting room does look like a waiting room as Groveraxle said. I like the idea of a built in banquette around the perimeter of your sitting room. It could be used for lounging or dining. Also, I think what's throwing me off (and maybe you too) with your open concept is the big couch closing off the kitchen from the tv room. Because your big couch acts like a barrier, you end up with a noticeable dance floor between kitchen and tv room. If this were my house, I'd move the big couch to the wall where you have a chair and move your 2 chairs where your couch is. That way you can move your chairs further towards the kitchen to use up some of that dance floor space. It's kinda hard to tell but I think the rug in the tv room is too small, your furniture looks all crammed around it. From your photos it looks like you have a nice spacious kitchen and breakfast nook then big furniture crammed around a small rug in your tv room.

I think I’d be tempted to lose one the lounge chair at the bottom left, swing the sofa and coffee table 90 degrees anti-clockwise, relocate the lounge chair at the top left to the position vacated by the sofa, then get a dining table with seating for six. Just a suggestion.

Instead of using valuable counter space for eating, I would prefer a table and chairs to the left of the front door as you enter. That would allow full use of the island counter for cooking and serving. A round table would soften the room and be easier to walk around in addition to giving you more “let’s squeeze in two more chairs” space when friends stay for lunch. Be careful ordering furniture before you are in the house because the measurements might be wrong. Slow down and enjoy the process of building a room after your move to fit your family and their activities. A sofa too long or a chair too skimpy will haunt you for years.

Thank you both! Jennifer, I just uploaded a floor plan for the area. It looks like the living room is 15x18. My husband and I were already considering putting a sectional along the left wall as you described, so I'm glad you see that as a good option, too! Beverly, I like your layout of the living area! Is there a reason for the rounded table vs. a rectangular table? I assumed a rectangular table would look better, so just curious. Thank you again for your suggestions!
