- Why are the drawers to the left of the range 33" and to the right 36"? Should they match in size?

The range is not centered under the hood. If it is shifted over to the right, the drawers on the left would become larger. Can the 2 door cabinet to the right of the right side drawers shrink? I would want the drawers to be the same size.

As far as the glasses/storage question, that is a long way to walk with every glass. I have glasses stored near the dishwasher, and I also have the bar glasses across the kitchen where the beverage center is. It drives me crazy having to put a couple of glasses in the cabinet across the room. I pull them out, put them on the island, then walk around and put them away. There is no way I would want to take every glass all the way across the room. I'm not sure what the solution for you would be, but that is my observation in my kitchen.

Trash location--my thought is this, if someone has the dishwasher open while cleaning up from dinner, and someone else has to throw away trash, or scrape a plate, they need to get between the person loading the dishwasher and the dishwasher just to throw something out. Or is there also trash to the right of the prep sink? I love having a trash pullout by my prep sink.

Ok, I'm not a layout guru, so I better just stop blabbing.....

You have already created sink wall that is not very symmetric. I would put the trash to one side of sink and the DW on the other side. Both trash and the DW on the left is not very functional, IMHO. I think you need to do some work on the sink wall. You need to either enlarge the window or fill out the blank wall with shelves or something. If you put a fabulous art work, it may work. But as it is, I am not sure how it will turn out.

I would move the prep sink to the refrigerator side of the island. As it is, both sinks are squished to the L of the kitchen and the R of the kitchen has no water access.

Why do you need so much space in front of the opening/door/sliding door on the R? Is that really necessary for traffic flow? That seems like a lot of wasted space.

layout help is not as meaning unless you tell us how the traffic moves through the openings: DR, groceries, garage etc. What is happening on the wall that is not shown? Is that open to the DR/great room?

I'm no layout guru either, but here's my thoughts:

Can you put the trash under the sink? Get an offset drain? Usually that's wasted space otherwise. But I would have another trash somewhere else where everyone else can get to it easily. Preferably near the refrigerator. And make it a double with recycling.And then you could put in a bank of drawers for silverware near the DW - on the end and move the DW next to the sink.

I agree that the DW is far away from where you plan to store glasses. Not sure how to fix that easily, but I agree it is not ideal. Right now I store coffee mgs away from the DW near the coffeemaker and it is a pain to put them away. And they have handles so I can grab a lot at one time.

I'm not sure about the lack of symmetry on the range wall. Not only are the base cabinets not symmetrical, the uppers and lowers don't line up very well. But maybe that's just me. And maybe why I parted ways with my first kitchen designer. Most of mine do line line up now, but not all of them and it doesn't really bother me.

You have such a nice space! Take some time and get it right! And don't assume your KD knows best. Its your kitchen, you're paying for it. And you have to live with it.

Ideally, if you're right handed, you want trash on the left of the sink (accessible from both sides), dw to the right. In your layout, that would put the dw in the corner. Not optimal.

Why not consider moving the range/hood to the current sink wall, and the sink to the center of the range wall with a huge window above. You could put glass uppers on either side of the sink.

Alternatively, you could move the sink/dw to the island, also not ideal. It would make me crazy to have the vent hood off center. Here's a question for you, you're open to anything, have a huge beautiful space you can configure any way you want, and this oddly un-centered, mildly disfunctional layout is the what your designer came up with. It's not horrible, but it's not great either. Why are you staying with this person?

Here's my list of what I would consider. Others have mentioned most of these, I think.
1. Range wall.
Drawer stacks next to the fridge. I personally wouldn't worry about symmetry in the base cabinets.
Center the range between the corner and the fridge and keep the wall cabinets symmetrical, which I think you have done.
Is the cabinet on the right end of the range wall a blind corner pullout? If not, why not use drawers here.
2. Island
Move the prep sink closer to the fridge, not across from the range as it is now. This would be a real nuisance if someone was cooking and another person was prepping.
Does anything go between the island and the windows to the right? If that is just waste space, yes, I would make the island longer and put a drawer stack in. Not so if you will have a table there.
Can you make the island wider?
Do you need almost 9 feet of seating at the island? Is the dining table right below the island? Or to the right of it? Even without lengthening the island, you could certainly use a 2' drawer stack on the seating side and still have room for seating for three if the island were wider. Drawers here would be a great place for table linens, among other things.

3. Sink wall
Why no wall cabs on sink wall? You can use the easy reach corner wall cabs here and it looks like another four or five feet of cabs between sink and door. That's a lot of storage to lose. And it's awfully nice to have dishes and glassware stored right by the dishwasher.
I agree with numbersjunkie about putting one of the trash receptacles under the cleanup sink, assuming there is another one is by the prep sink. Most of the trash is generated during prep. And you could certainly use another drawer stack.
I understand wanting the sink centered on the window which means that DW and trash, if that is what it is, must be on the left side of the sink. Certainly not optimal.

Overall comment:
1. You only have 5 deep storage drawers. I would really try to find space for more. The little top drawers are nice, but don't hold much. I had no idea how much I would love drawers.

I'm watching the Olympics as I type this. Hope it makes sense.
