I would think the left cabinet of the set of 3 would be hard to reach, but you could store things you don't use often in it, like serving pieces? The only option is to reduce the size, and then you lose the storage completely, as well as the look you love.

i think it looks good. is the doorway on the lower left wide enough?
how about drawers under your 1 dish cabinet for other dishes? well, maybe not until kids are older... except for plastic ones - which are often used with little ones anyway! plastic in the drawers, glass etc in the upper cabinet. are you putting mostly drawers in the base cabs?
i hope you're tall enough to be able to use more than just the bottom shelf of the uppers - lol! I'm not.

what's next to the refridge?

What about another upper (open shevles) on the other side of the main sink. It's in a corner and I don't think you would lose your openess. It would also balance your sink and window with the other shelf on the other side - and it's really close to your dishwasher.

I think that's where we're at, with rarely used items. Thanks for chiming in on the color too. We're doing some green, at least the pantry or the lowers.

The doorway is 30" (or will be, I may have bumped it down to 28" at one point) and will have a dutch door. One of the reason we didn't plan a lot of uppers is that my wife can only get to the first two shelves. I love the look of 39" uppers or double uppers to the ceiling but she finds it mildly demeaning that half of her kitchen would be out of reach, so I did soffits and fewer uppers. As for what's next to the fridge, I had a poll up on that too:
Fridge pantry or coffee station options

My wife is a little gun shy on having all open shelves (because of the clutter/mess) so that cabinet was a compromise. I can draw it up with shelves though for comparison, because I think you're right it might look a little more balanced.

I can only reach the 1st 2 shelves (I'm 5'2")and I'm getting 42" uppers. I will stock the upper shevlves with little used items. I'm actually having my uppers installed 16" above the counters and hope I can also reach the 3rd shelf if it's not too high. I don't have any appliances that would interfere with the lower height. I would hate to waste all the storage space to a soffit. We will have 9'6" ceiling and crown moulding and lights above the cabinets.

The right hand door opens into the hood. The left hand door makes the cabinet hard to use from both sides of the peninsula. Consider reversing the door swings?

I would encourage you to consider making the eating space counter height and move the prep sink into the corner. This is for a couple of reasons. I don't like how raised bars play out - they have access problems and they rob you of a big flat counter area when you need one. We had one and it was the first thing removed from the new kitchen.

The prep sink move is to have some landing area for items from the refrigerator - right now, you either walk or put them IN the sink. Also, it puts it at the stool position that wouldn't get used anyway cause of the upper cabinet in face.

In your case, I think the raised bar will make the kitchen look even smaller.

Lastly, be sure of the order of ref, oven, pantry or the reverse or ref, pantry, oven or its reverse or... There can be a problem with the ref and oven opening into each other. I tend to place the ref close to where I think people will come from to get a drink.
