Were the cabinets custom? If they were custom the cabinet maker should have been able to center the window.

the end cabinet may look better after the countertop is installed, depending on the overhang.

When you say the windows aren’t centered, do you mean the windows aren’t centered on the wall? Or that the cabinets aren’t centered under the windows? Does it match what you signed off on?

And for the gap in the wood by the fridge, do you mean that gap above the fridge? It might be necessary for air circulation. If not, I’m sure you could get a trim piece to cover it. But if you’re referring to the gap on the right side of the fridge that looks wider at the top, that might need to be addressed. Either that piece is not straight or the fridge isn’t (maybe one foot is raised higher).

What do the plans say? Is the window supposed to be centered over the sink with the cabinets equidistant on either side? Is there supposed to be a gap between the fridge upper and the ceiling?

The window would drive my crazy. Do you need those thin uppers on either side of the window? I would consider pulling them down, then the window issue possibly would not be as obvious. But your once your faucet goes in, it might throw it off again.

Looking at that window off center above the sink is making me twitch. I would not be able to accept that. It's not too late to fix, but it will be soon, so yes, you must speak up. You may need to replace the cabinet between the fridge and sink on the left with the same size that hangs above, and just add a spacer to accommodate the extra space. Looks like you already have a spice pull out on the other side?

The gap at the top right of the fridge might be because your floors aren't level, but it's worth calling that out too, to be sure it's not a warped piece of board. Also, have you tried opening those corner doors alongside the stove? Is there enough clearance?

Be sure you test that your refrigerators will open all the way.

Symmetry is overrated. Put a 60/40 sink in there and it will be so mixed up it will look like you planned it that way.

Is the refrig and the cabinet on top overhanging into the doorway? It may just be the angle of the photo but if it does, that's about as poorly planned design as I've ever seen.

Who designed this? And picked out cheepchinesecrapola cabinets that don’t have blind corners to be able to make this work.

Thanks for clarification on the sink location. I'm thinking maybe once the countertops are on you won't notice the off centered window as much. Hopefully you'll be able to camoflauge (sp?) in some way once everything is done.

I would sit down and have a conversation with the contractor. I wouldn’t expect to pay him the full amount for work that does not represent what is in the drawings.
