I asked a more specific question but everyone just wanted the whole story, so I've included my floor plans and current layout below. The thing we are changing that revolutionizes the room is the windows. Currently there are two windows (with non-supporting trim in between) that are both wider and lower than the cabinet depth and height so we have these odd open cabinets at the end that are very hard to use. I want to replace them with one window that's either 60"x48" (and is higher than cabinet height and would allow you to run cabinets along that wall) or 48"x60" (and is narrower than cabinet depth if you keep it in the galley layout so you can put full size cabinets on the end). This is a main window for a larger room, so I want to keep the overall window area the as close to the current as possible for light. The light blue side (bottom) is open to the rest of the room and the top and right walls are solid brick so putting plumbing there would require giving up some square footage to furring out the wall. My strong preference would be that the range and sink move as little as possible from their current position (or at very least stay on that wall) and that we reuse the cabinets we currently have (2 18 inch cabinets and a 36 inch cabinet) to avoid waste.

Let me know if you have questions!
