Any suggestions please?

Is this a new build or remodel? Where do all the doors go?

How many people typically cook in your house? You have a lot of room, but everything happens along one wall. Putting the sink on the island would help.

Your aisles are too narrow - especially for seating in what I presume is a walkway (since there is no wall shown on the right side). The aisle on the sink side is just barely tolerable if there is only ever one person in the kitchen.

The crown molding looks massive, out of proportion, and expensive. Do you have 9' ceilings?

Start below and reconsider the layout. I would probably remove seating from island and cut it down by 8 inches and add those inches to the walkways on either side. 48" being minimum isle especially for side with sink and cook stove.

ice, water, stone, fire, police: I added my own ending to mean clean up/restore to order/restock etc...

see if 8 or 9 foot island would suffice. move it over to the left a bit also. I would turn the corner at the right end of the run beyond the sink to give a small L at that end of your long run. Not exactly a full peninsula but give yourself a stack of drawers and some counter. Then I'd eliminate the stuff between the two doors on opposite wall. I'd do a pantry next to oven stack. with the freeing of the space between the two doors I think the island could be pushed back to increase the main aisle of the work area and more room for stools w your overhang .

@AnnKH @Rawketgrl@herbflavor Thanks so much for your responses.

@AnnKH It is a new construction. Here is the snippet of the plan showing the layout of the floor ( right side is family room, left is dining room, the door in the middle is a pantry). In the pictures I shared, the KD has moved the REF to the left of the stove than what's shown here. Yes, we do have 9' ceilings. The crown moldings have been included by the KD in the first drafft, but we can change that to something simple.

@Rawketgrl Thanks for that link, very helpful. At this point, we can make some modifications to the layout but not a lot though. House framing will start next week. Great idea to make the aisle 48' on the stove side.

@herbflavor thanks much. We were also thinking of a small L at the end and perhaps the REF can go there? We do have a walk in pantry in the plan.
