It is really hard to visualize without pics. I know you aren't in the space yet, but could you at least link to a pic of the dining set? And the sofa? And a photo of your chandelier since it sounds like you have that in your current home? It sounds like the kitchen is a black/white color scheme. A lot of people pair that with greige walls, which (if my web search turned up the right sorts of images for "mink") seems like it would work with your dining set. I think "fawn" walls would not work well with "mink," at least if my understanding of what you mean by those colors is on point. Fawn conjures up a warm color with orange undertones, and while that could look nice with a sage green living room set, I think it will fight the cooler tones of the kitchen and the proposed dining set. It sounds like the peppercorn floor is not installed yet, so I will throw this out there: Dark floors have a reputation for showing every speck of dust. The elements you've described would look just as nice with a less dramatically dark floor. Just something to think about. I haven't found it to be difficult to find black tables in styles other than country. What style are you interested in? More modern? More traditional? I'm sure we could help you find something. But if you stick with the peppercorn floors, black furnishings might be too much black. You could do white (tie in with kitchen cabinetry), chrome (tie in with your proposed chandelier) or something else. Congratulations on your new home! (I probably should have led with that...)

THANKS FOR THE PHOTOS, I WOULD NOT RECOMMEND A BIG AREA RUG IN THE CENTER BECAUSE IT WILL UNBALANCE THE DINING CHAIRS EVERY TIME YOU USE. YOU CAN ADD A RUG UNDER THE CHAIRS IF YOU HAVE ENOUGH SPACE A FOOT REST WOULD BE NICE IN FRONT OF IT. SOME INSPIRATIONAL PHOTOS MIGHT HELP

Okay - did the corrections and think I have a close approximation of your space. Each block represents 1 foot. The gray area is the space needed around the island for walking with people seated - should be clear of furniture. Can you take a picture of the full wall where the fireplace and tv nook are - not sure I got their placements right. Do you plan on using the tv nook for the TV? How did you envision the living/seating areas when you designed the kitchen? How many people need to be seated - do you need a dining space and how many people need to sit at the dining table or are you just using the island for meals?

My second comment is everything is priced high right now. I would wait. There is a lot of furniture for sale in every state as the largest move is taking place in the USA   Homes are selling with furniture, people are selling what they do not want to move. Ebay Craig's list Next door Neighbor Chairrish 1st dibs and local shops have a large assortment. Look around you might find something or work with what you have. Prices are starting to settle back down. I think your room is lovely A dining room is where the family will never notice what the colors are, only the day. The fun, the silliness and Mom's favorite dish being served. Enjoy it all
