Please create a plan in 2d with all measurements. We can't help you without a 2d plan with measurements

I know that I"m in the minority here, but I'd give up that island and its seating in order to have more counter space. I'd come around the corner, making the counters U-shaped. Then, I'd buy a small island cart such as they sell at Ikea to use as a landing zone in the middle.

I'm just not an island fan. I don't like eating at them (reminds me of the lunch counter at Woolworths when I was a child), and they take up valuable real estate than may not be gained from the island itself. My daughter has an L-shaped kitchen with an island, but it is a separate kitchen -- no open floor plan - and the opposite wall holds the oven and microwave, plus bookshelves and storage (and a cabinet for the cat box!). My son had a huge island in his last home and the children always ate at it even though a few feet away was a charming breakfast room. There seemed to always be a lot of pushing and "move your elbow" going on - far easier at a table with each person have their own place. A table also encourages families to sit together. But then I'm a dinosaur...

Turn the pantry and dining room into your kitchen....you don't need that pantry. Make a nice big U kitchen once the pantry is erased....you have almost 20 feet length total. Place dining zone where current kitchen is shown. You can make the U kitchen into a G if you want with the extra arm of the G forming a peninsula of sorts with some seating around it. You have a big enough laundry to stack washer/drawer, add shelves for overflow kitchen storage. The great room now encompassing living and dining with kitchen offset would be nicer for people moving between seating area for eating and living zone.......the action of the kitchen is adjacent but slightly out of the sight line in your big social space...which apparently you have committed to at this point. Dining in the small bump-out you made has poor sight lines to back hallway and end of your kitchen runs....you can make this better once things are shifted.

Are you able to have a second sink?

Without measurements (but based on your island of 9'), it seems like the kitchen is plenty big and has ample counter space.

You can go from fridge where you have it to prep sink on island to stove on the long perimeter run and cleanup sink on the shorter run.

Or fridge, prep sink on same wall, stove on shorter wall and cleanup sink where you have it on island.

If you are not interested in two sinks, I'm aftaid some of your counter space will be wasted. Where is the stove proposed on your plan?

Hard to tell without dimensions but in your 3D view it looks like the sofa is about 18-20 feet away from the TV and there's a lot of empty space between the TV and the furniture. That's a long distance. I realize the furniture layout on this plan is conceptual but maybe by drawing it with the seating area 2 or 3 feet closer to the TV the area between the sofa and counter won't look cramped on the plan?

I think I have about 19 feet in the living room so the furniture probably will be bumped up some. We could do 2 sinks. I don't see the purpose of having two but it seems alot of people do it. Maybe going to a smaller sink in the island would allow me to shrink it some. I think I was planning on a 41 inch deep top with a 15 inch overhang. Ill work on something in 2d.

What is the little square space in the middle-next to the staircase? It would be nice to be able to recess a full depth refrigerator into part of that space (depending upon what it is).

Recessing the fridge where you have it drawn is a great idea, near the pantry and the garage entry (where I assume groceries will be brought in). I'd put the DW on the end of the short wall, so that it's separate from the prep and cooking zones--a helper can load and unload the DW, or set the table, without interfering with your prep and cooking activities. Put the prep sink on the island, and center the range between the fridge and the wall to the right. (emilyam's first suggestion)

It appears that you have an upstairs--how will you vent the range hood?
