I love the clean, uncluttered look of your home and you've made some great furniture choices. My first thought, though, is that I would try to rework the sofa/sectional placement. It really is unwelcoming looking to me to have the back where it is facing a wall, when it could be oriented to look into the room and out the windows. It seems like if it were placed in the corner under the stairs that it would feel open and invite you to come in and sit. I'd hate to be cooking in the kitchen and have the family or guests with their backs to me. If you are having a TV in another room close by, do you need one in that room, too? If, so placing a 70" unit will probably only work as you have it. But, to me, it's not going to look like a living room but more like a movie theater, which is fine if that's what you're going for. It seems like it won't be a cozy conversation area, though. I might actually flip the rooms and put the dining room where you have the sofa now. I was looking at lights used with dining rooms and ghost chairs and saw this, maybe would work in the living room? Kind of fun. don't know if it would look as good without the colored walls though. And I thought something like these were interesting to consider for over your table:

What are the big red scratch-outs? Furniture you aren't keeping? First step is the couch, second is the rug and third is the paint. Paint color should be based on fabrics and textiles (seating and rug) in the room. It can be custom blended, but the furniture is set in stone. When you shop for the rug, it should be 2-4 feet wider than the sofa. Slip it under the front 1/3 of the sofa and have it extend past the ends by 1-2 feet. You can use painter's tape on the floor to figure out the best size for your sofa and room. I'd replace the dining rug too, so the two are coordinated. In addition, push your TV credenza against the wall and put the TV on a swivel base to adjust for viewing.

Hi Patricia, Thank you for your response. Can you inform on where i can get a detail floor plan. Is this something i can do online or will I have to consult a designer. Thank you again.

I don't think the top rug is going to work with your floor AT ALL, at least if the colors I'm seeing are halfway true. The gold in the rug is just going to make the floor look purple. The second rug is a maybe, as it has a variety of colors including some cooler tones.
