I measured roughly using the 20"20 porcelain tiles as my tool and here is what I got. The living room is 13 1/3 ft deep x 18 1/3 ft wide. The window is app. 10ft wide. We are replacing the window with one that will have a larger center picture window and a smaller sliding window on each side. The normal arrangement for furniture is the back of the sofa to the window, centered. Two chairs angled on the wall where sofa is now in the pictures. An old recliner is in the area to the left of window as you enter the room. There is one bookcase that I now have on the wall that you face as you enter the room from the foyer. It's in the left corner with a small round table on the other side. Coffee and end tables too. We used to have an upright piano that took up alot of space but that is now at my son's house since he is the one who plays. Interests, hmmm... I am into genealogy and the bookcase holds pictures of ancestors. We also have two portraits of ancestors on the formal dining room wall, same wall as bookcase and its also the wall with the buffet on it. In the formal dining room, I also have two shadow boxes with engraved antique silverware from my husband's family, plus some other family treasures. We live in Florida. Most houses the age of ours are similiar. Our house is one of the larger homes, although not as large as many of the northern peoples' homes here on Houzz forums, or as fancy. I just want something that fits with the porcelain tile that we chose ( we have two dogs that love to run and play). I had wall to wall and just got sick of it. I love my area rugs, I know, not an in color that is "in" now but it will stay. Window treatments will change once we decide what to do with the furniture and new windows are installed. The walls are Pewter Vase - I thought it was a Sherwin Williams color but my paint strip doesn't say that. Its a nice netural gray, doesn't read purple in the room. At one time, I had thought about putting causal furniture in the room, without any area rugs. That was when my first grandson was a toddler and we used the area for floor puzzles and playing. However, the tile was too hard to sit on and we had an echo. I have another toddler grandson now and we have enough space for him to push his toys in a path around the foyer, living room, dining room, kitchen and into the family room. I don't forsee it being a problem to get new furniture but its another reason to consider price and style. Thanks for the comments so far. I appreciate your help.

Is the soffit which divides the two spaces painted a different color or is that just the lighting? The built ins are beautiful. I love the paint color! Can you tell us what your style is? Do you like straight lines? Do you like color? Of the top of my head I would say rich color rugs, curtains and lots of lamps. Those are the things I always want in my home. Not to mention art. The rest falls into place. I guess to suggest we need to know what you like and the feeling you want in the space.

Near the entry door I like to have a bench to sit on when putting on/taking off shoes. Also a console table with mirror above it. So think of creating three zones - entry zone, sitting area, and dining area, while leaving at least 36” of walkway along the side of the room. I agree that the chandelier will probably need to be moved over to be centered under the dining table, and perhaps it could be replaced with one that is more of a focal point since the room seems to be lacking one.

Formal/elegant for a formal living room space, yet also functional and comfortable for lounging, TV, etc. Uh, that encompasses a lot of choices! And, you provide no picture of the space, the size, the kitchen area, or any thing else necessary to advise you? Like color? Budget? Preference on style? is there a fireplace? what kind? how will seating be arranged? do you need a console? do you want a farmhouse style, but on the formal side? or do you want more formal without farmhouse? do you want muted tones or color? maureen gave you some nice choices, but honestly, without pics AND more infor from you, we're throwing darts in the dark.
