I agree with another poster that a silvery grey on the walls would look wonderful with the wood-tone of the floor. However, a neutral light blue also would look nice because blue is the complementary color of the brown in the floor. If you have a grand piano, I would suggest you place it across the corner that is to the left of the large window unit. I would suggest you leave the large framed mirror where it is, and you might find two additional matching mirrors you could place on the wall behind the piano to reflect the light. I would suggest you move the dark-framed collection of small pictures to a place where the entire set can be viewed more easily. The dark frame would look nice above a low bookcase about 48 inches high, provided you could place such on a narrow wall next to a doorway, in the foyer, or in a hallway. A small sofa would look nice under the single framed mirror, and it would provide excellent seating for your "audience" whenever you play the piano. An occasional chair in a matching upholstery or even a bold accent color, placed across the other corner of the room, would complete the look.

j, I'm going to tell it the way I see it. It never makes me popular but I'd rather be honest and give you good advice rather than have you go down a very gnarly road. First thing on MY agenda...You spent well over $5,000 for your dining room table and chairs. Personally, I'm not a fan of EA, but you have a really spectacular look and quality in those pieces. It's the first thing I noticed when you posted. I had no idea it was EA. I thought it might have been another vendor. The LOOK you achieved with that purchase is far and away a great price for the results. So now, here we are with the living room. I know often times that clients set a certain value on individual pieces because that is what they know as being a fair value with the promise of quality. I would rather you do absolutely nothing with your living room rather than throw good money after bad. That gets very costly over time. You purchased the two Macy chairs for a very FAIR price and the reason you bought them was to fill the room and to not spend a lot of money. It is interesting that your budget for a sofa was around $2,000. So this is not about budget much as it is related to what is considered fair value in your mind. There are $300 chairs as sandraclark has pointed out and there are also many sofas available for much less than $2,000. The two tables you purchased for the foyer and living room have absolutely nothing in common with your intention for the dining room. The dining room and those two tables (console and coffee table) belong in two different homes. The tables would work very well in a family room but not in your living room with the dining room as you have designed it thus far. I would suggest you do nothing until such time you decide you want to achieve the same quality look in each room. I very much like the idea of the 4 chairs for starters and for you to add more pieces and accessories, art, etc. as you go along. The chairs need to speak the same language as your dining room. That would be a modernized interpretation of traditional furnishings. This would not be mid-century modern attempting to go traditional. I have examined this and I have attempted to make what you have chosen (on the fly) work. I could encourage you to move forward with your choices and waste more money on a look that just can't be what I know you really want. I would much rather you rethink your long term budget and get a really good idea of what the costs are for items you would really like and if it takes waiting then that is what you should do. Just filling up space to get it done and at price points that seem to make sense at the moment will leave you with an area that will have to be redone sooner than later....and that is just not what any of us wants. We want to do it, get it done, put it behind us and not have it all revisit us in 3-4 years. My opinion of course. I really, really care so that's why I'm writing this ridiculous tome.

Avoid sectional. They are not flexible and you will live to regret it. Sofa and chairs best bet. Sofa facing fireplace, but would still look out windows and see TV. Like idea of units each side of the fireplace, but I would prefer furniture pieces instead of "built-ins". They just look so "builder" to me. TV should be where light has least impact on screen. A pair of swivel chairs in front of windows would allow for TV viewing or "view" and quiet time. Oversized coffee table would really look fantastic. Sofa table so you have more to look at looking into room than back of sofa. So, in any case, very nice space to work with. Glad the arches are going, going, gone! Hope gas line is able to be rerouted without too much hassle.

I think the rug has potential. The navy blue color needs to be emphasized through accessories like throw pillows, lamps, or even a throw blanket. The dark color of the TV stand and the coffee table aren't blending in with what you have. I would suggest buying white, or different shades of blue, table accessories. Try looking for a mirrored table tray that you can place vases with fresh flowers on or some holiday themed candle holders. The photo isn't necessarily ruining the room. If you painted the frame white or another light color it would greatly change the way it interacts with the flow of the room. Try to mix in some white accessories to also bring out your white trim.
