The top door goes to the office, officially dining room, but we used it as office. The bottom one goes to the entry way (front door).

No windows in the kitchen. Window is on the right, bay window.

Yes, the wall is not load-bearing.

Yes, the current wall oven needs to be replaced (the door's a bit bent on the hinge), and I checked online, replacing the wall oven cost as much as replacing the whole unit with slide in or freestanding range. The wall oven came with the house. The drop in stove was replaced maybe 7-8 years ago, but at that time the appliance insurance paid for it with very minimum budget, so we got the very basic model. It still works, and we wouldn't mind keeping it, but since we need to replace the oven and it costs the same as freestanding range, might as well get a new stove, too :)

With both option, I'm thinking not to have the fridge panel/surround, but have cabinet above.

Thanks!

option one might interest me but swap stove and fridge..as well, work in a cabinet depth fridge, or plan to recess it. Second tweak would be the cabinetry on the left side area toward dining /office room. This is shown at 60 inches with full depth apparently. Modify it with reduced depth and perhaps reduce the 60 inch dimension. Can the 7 foot wide sink run be extended into the unused area off to the side? that would be a benefit ...the full depth on the side wall is not so useful, if it were my choice.

I like the swapping fridge and stove idea. I cannot make the island too wide, because it will take up too much of the dining room space.

What if you went back to your original layout, but increased your aisle width to 54 inches. Leave a wall on the sink run long enough to hide the fridge. Open up the doorway between the dining room/office enough so that the fridge cab can be against the wall. Then make your sink peninsula 36 inches deep and put shallow shelves facing the living room on the sink run. I would be careful not to run cabinetry too far into the breakfast room.

i noticed the wall between the kitchen and dining room where the oven was is 26 inches. Perhaps the fridge would work there too and then your sink run would be very generous. You could do upper cabs on the side wall. I think your island/ penn should be at least 36 inches deep so that you can put storage on the living room side.

I cannot open up the door wider, I have furniture and stuffs right behind that wall.
