This design is awful. Why are your refrigerator and cooktop smashed into the corner?

I have no idea, but that's how it was designed. Originally there was a microwave/double oven to the right of where the skinny pantry is, but the range was still next to the fridge.

Where are you getting your cabinets from?

Most likely custom

Start OVER.

Rather than these elevated program "drawings", do a flat on paper plan showing all dimensions of the room. The ENTIRE room. Include existing windows, and entryways to the space, and inform us of what are adjacent/behind spaces. Post it here. Trust me, none of the above are good. Post a photo of the existing kitchen as well.

I agree an actual floor plan is always the best IMO for beginning to design a kitchen. IMO you need to have a good KD along for this . I would not block off a window for a pantry , the range should go on the wall between the windows to be on an outside wall there are just better ways to design this space.

For instance you could put your cooktop with a beautiful hood in between the two windows flanked by upper storage cabinets and it would be the show stopper for the room.

Or even something like this with no windows

Here's a photo of our current layout. The only difference is that we painted the walls a light gray and the floors are now wood.

I like #2 with the fridge moved right up against the pantry so that you end up with nice space around the stove. But that depends on whether you're really willing to get rid of the window, and/or really don't want to move any of the main water and gas lines -- otherwise, stove between the windows, fridge surrounded by pantry cabinets seems the best, and you continue the counter across under the window. It's hard sometimes to think in "from scratch" terms...

Your current kitchen is very nice, have you thought about having them refaced?

What is your hesitation in putting a sketch up with room dimensions? Without room dimensions.......as above, it's just idle conjecture on my part : ) and everyone else's as well. If you called a kitchen designer to your home, they'd bring A TAPE MEASURE.
