I drew this to help myself visualize--my thought was to center the hutch/oven build out on the wall and then use uppers to balance the window on the other side. I think this is what you were saying? Thinking I will shorten the island on the dishwasher side by a few inches and do a waterfall countertop over the short edges. That way I can get rid of the build-out over those sides and neatly cover it off, while making the dishwasher area feel a bit less cramped. What do you think?

Thank you all for the super valuable feedback. I would also like to take your advice on pendant lights, given that we are looking to go with white island and black granite. We need two pendants above the island and one above the sink. I was thinking of keeping same fixtures above kitchen and , which have simple look, to not add too many things. Can you please share your opinion on the attached? Or make a suggestion? Thanks again for all your help. Here is the link to the fixture: https://www.wayfair.com/lighting/hd0/amara-2-light-dome-pendant-l6087-k~wlsg2727.html?refid=GX263467579172-WLSG2727&device=m&ptid=470146491070&network=g&targetid=pla-470146491070&channel=GooglePLA&ireid=56904236&gclid=EAIaIQobChMI5PnQyvTx3QIVwWSGCh3TYApREAQYASABEgLBLPD_BwE#ek77z7p7lw-3

First, I would reduce the width of the island, especially if it is moved out another six inches to provide a 48" work aisle. You need at least 36" of walkway on each side, between the back corners of the island and the walls framing the FR. Second, add a pull-out cabinet between the fridge and stub wall, to make sure the left side fridge door will open fully. Then, if you move the range toward the window, on the left you can add a glass front cabinet the same width as the window, and have symmetry. On the other side of the window, widen the uppers to the width of the fridge, and reduce the width of the tall cab. Center the island sink on the range, with both DWs to the left (as you face the island), where it will be easy to unload them to the perimeter cabinets. Put the trash pull-out to the right, in the primary prep space, with a MW drawer on the end near the fridge, since most MW'd items come from the fridge. MW could open to the side, to keep anyone using it out of the primary prep space. Many don't like a sink back-to-back with the range, but the most time is spent prepping to either side of a sink, and a 48" aisle is sufficient if two people are working at the same time. I'd omit the peninsula between the kitchen and breakfast nook, unless you feel you absolutely need it for serving or storage. The UC fridge can go in the corner, with coffee pot on counter above.

Note this home is on a concrete slab so I will have to be creative in getting electric to my prep island. The electrician and I discussed running electric down a conduit doubling as see through shelves on the SE corner of the island where the bookcase is on the sketch. I want seating closer to the stove and trash for when my legs and back start aching from standing. The 2nd seat would be for when I need reinforcement on food prep and cooking! I'd rather have touchless trash but will deal with pull out if can't figure out where to put it. I want to keep the sink in front of the window since there is usually plastics and pans in the sink waiting to be hand washed. will the frig and dishwasher be ok next to each other? (I really don't see any other way) I'm attaching the way it looks right now (2 even with taped out areas representing the islandand the fridge)...basically a mess
