Just wanted to update this post again to say that I moved the couch back in today. The room just felt really bare and impersonal without it! And sharing 1 couch when we all like to stretch out and lay down wasn't working. So, I brought it back in but put the TV in front of the fireplace like Les suggested. I actually had it this way before, but changed the layout when I bought my Christmas tree. I just never put it back. I will look into options to cover the fireplace entirely because I like the layout of the room better this way. Will now work on getting some lighter curtains for the doors to bring in more color and also figure out how to hide my phone/TV cords better. The ottomans have seen better days and they will be replaced soon....they'll work for now because they're purely decorative. I'm going to buy some throw pillows and replace the wood that's in the basket by the TV cabinet. And I'm going to bring up my matching floor lamp that's currently in my family basement room. I'm back at figuring out wall art, but I'm going to try to add something to the walls too. I also plan on buying a couch to go in the library since I moved this green couch back in. I'm open to buying a couch that will suit this room better if something else will work better. If you all have any recs based on the pictures, feel free to share. Thanks again for all of the great feedback!!

Would def not switch the rooms for reasons stated above. Would use a round table in that space, I think, or a rectangular one positioned horizontally as you propose, fairly close to the proposed pass through to the kitchen. I would also make that an arched pass thru and a little larger if possible. The obvious problem with the fireplace is that it curves far into the room and takes up more than its fair share of floor square footage. With the table placement as you describe you might get a few chairs in front of the fireplace, but even that may look awkward. I think I would open up the room as much as possible to the FR using an ibeam and not columns, which would only further visually confuse the room. Then I would look for, or have made, a curved bench to sit a foot or so from the hearth. Depending on your decorating style, this could be a fabulous brass fireplace fender with leather cushions, or a simple upholstered bench. Both would be low and of course people would sit on it facing the room, making the FP more of a backdrop. Anything else is going to be tricky in terms of furniture placement, as the radius of the hearth will dictate having sofa and chairs far enough away from the heat source to look odd. The layout looks interesting, but complicated. If there is a good interior designer in your area I would consider hiring him or her just to help you sort out furniture placement. And I would consult,the person before your GC makes any structural changes. Good luck with your project!

Do you have plans for the niches next to the fireplace? Maybe builtin storage cabinets and TV on a pull-out swivel on the right. The L side you could leave blank or have shelves above the lower cabinet. It will add some architectural interest and allow for storage. Then a seating area in front of fireplace - sofa and 1-2 chairs. A small desk area in the space between sofa area and dining. Though I’d probably have a computer station that closes off (do you need for desk top or just lap tops?)

@Beverly the table is a 79" x 39" 4 person table and it actually doesn't extend past the dining room area, I can totally see how it looks that way in the other photo. The dining room is 11'11" x 9'6" wide. The table is closer to the living room side as the light fixture is mounted off centre to accommodate room for a sideboard/allow space to walk around the end of the table on the other side - hope that makes sense. We have tried moving the table over the the right (closer to the other wall), and it still doesn't seem to alleviate the awkwardness of how close the fireplace is to the dining room window/dining room window. Please don't judge the dirty curtains... the dog puts his nose all over them. I hope this photo helps and maybe you have other ideas?
