Here is my first cut at your space. Rev. 1 (and btw, super-duper measurements!! kudos!). I put an approximately 11' length of sofa along the wall and since you have that short wall before the windows, I put a large ottoman type piece. I put a swivel chair in "corner" of the living space near the windows so you can swivel to converse or watch TV? maybe, or swivel toward windows for views. I put a 60" long (max. to maintain walking space to other part of the apartment) and keep it 16" deep because it will stick out 17-18 with baseboard, cords, etc. Set TV on that console. I put a 52 x 30 coffee table that would be 18" from the front edge of seating area. You could also put a small round decorative stool/table, beside the swivel chair for a place for someone to set a drink/cup of coffee, etc. Now to the dining area. To get a nominal seating for six in this area, you need a 30" wide table and you might have to have it made. A live edge custom table with metal base might be great in your space if that is a style you might like. Then in the living area, go modern and sleek. I would do the coffee table, even smaller if you wish with glass top and metal base to work with the dining elements you select. The chairs at the dining table have to be really narrow across the front seat edge. That is the big challenge. This table is 60" long and 30" wide. For every day, 4 chairs could be placed there, two on each side with the additional two chairs in the corners just to give a more open feel and help maintain views. You will need some additional lighting and a arc lamp would work well on the fireplace end of the sofa and you might want another floor lamp beside the window end of the TV console. Unless you shorten the sofa on the long wall, you have no space for end tables and lamps. So something to think about when shopping. I put a 36x16" bench in front of the fireplace for one person. The seating area will only seat 5 so total would be 6. You could bring in a chair from the dining set if needed and just squeeze folks in. Watch the size of cushions for any sectional you buy, each person needs at least 24" of space, and generally don't like sitting next to each other. Also, TIP, make sure your sectional pieces join together "under" the pieces so you don't have brackets on sides. This allows for greater flexibility in "next" house and even if you just want a seasonal change of some kind here. I'll play a bit more with this later today and see what other options I can come up with for you.

I guess I would start with the kichen being complete and that needs to done after the same flooring is installed everywhere I really am having some difficulty relating the pictures to the floor plan. In the pictures where is the mud room?

So part of the appeal of RH style for me is they incorporate rustic, organic, industrial, or antique elements into a space that is mostly monochromatic but full of textures. Some characteristics of their style are oversized pieces, as large as the space allows. Large artwork over the sofa, often in black or white or an abstract. The largest rug the living room can hold. Statement light fixtures in every room. Natural fibers and neutral tones. Decorative elements that are large but fewer of them on display, often incorporating wood or metal. What about something like this for a coffee table?

I don’t think the fixtures above your island have to match exactly with the pendant over your table. BUT, I don’t think the 2 options you’ve chosen work together.
