You have some good ideas but if you're going to sell soon and aren't planning on taking the soffit out, I would just do some minor changes and keep the cabinets (just add a couple cabinets). I wouldn't move the sink but just get a nice stainless steel sink and update faucet. I'd get a stainless stove vent. Remove the wall on the left of the refrigerator but then just do a small pull out pantry on the right of the refrigerator. And, put a cabinet above the refrigerator and make it look built in. A glass backsplash, can lights on the ceiling and pendants above the penninsula. I think a raised counter will make the kitchen/room feel smaller.

[houzz=] Here is another that uses the corner well. This also will help offset the lack of symmetry on the range wall as well. Your cabinet maker would need to work out all the measurements. The base drawers to the right of the range may need to be reduced in size to be the same as the ones on the left, which will also help balance the wall. This tall unit to the left of the range will help to balance the large pantry on the right. Where the below picture does not show it, you would have room to place a small matching wall cabinet to the left of the corner tower to balance and to balance out the space between the window. Then you can still have some type of unit to the left of the sink with the appliance garage, but it would not need to be quite as wide and would give some space next to the sink. Look at this more and see what you think. There are some very unique features to your plan. A very high level of customization and much thought has gone into it. It is going to be beautiful. Would love to see the final plan and pictures of the final product. Let me know if you want us to look further.

I would balance the fridge cabinet wall by having the fridge centred between two narrower pantry cabinets as it currently feels far to heavy for your space. Alternatively, I would recommend having a narrow pantry on the left of the fridge with a full height cabinet with counter on the right with an upper cabinet above. This would help your space feel larger.

Any pictures of kitchen, design?
