I would try another full height, shallow depth pantry cabinet, rotated 90 degrees to it backed into the other pantry cabinet. Same thing with shallow bookshelves and with angled corner shelves. Also maybe try two full height, single door pantry cabinets or slightly smaller full height pantry cabinets with wine bottle cubbies between them on one side of the ref. It's really hard to tell aisle and such from a perspective drawing - they can be really misleading. So take this will a little salt. It looks like you have about a three foot aisle between the fronts of the pantries and the peninsula. Even if you get a counter depth ref, it will still come out into the aisle about six inches including the doors and the handles. Plus another inch or two will go to adding decorative panels on the end of the peninsula cabinets and the countertop overhang. So you're aisle may turn out to be more like 28" there. Can the ref be maneuvered into or out of its place without removing the peninsula? Can you open the freezer completely? Are you ok with having to close the freezer door, walk by it and re-open to reach something on the other side?

Your layout is actually very similar to what I just did in my kitchen, with my island being smaller -- at about 4x7ft, and the space accordingly smaller. Works great for me, and I like your space! Moving the DW to the right of the sink is important, I agree. Another thought. I'd consider pushing your cleanup sink down the wall towards the right instead of centering it. When you design your cabinetry, you can center something lovely if you want a focal point there under what I am guessing is a window arch of some sort? (Maybe some special cabinetry stuff -- like a baking center . . .) Pushing that sink (and DW) down that wall will open up more nice prep/baking/etc space on that main wall and provide sink access closer to that entire right half of the kitchen. My sinks and cook top are laid out just about exactly as yours are now (except the DW on the right), and I generally use the island sink for cooktop water, etc. Only down side is that if you're making a mess by the cooktop, you do have to drag all those sloppy onion peels, etc either across the aisle to the island or a ways down the counter. Works OK for me, but something to consider. IMHO, your "work triangle" that is drawn should include the prep sink instead of the clean up sink . .. so, your work triangle is actually quite compact, so I wouldn't worry that the clean up sink moving right would make it too long/big. Depending on what that arch feature is on that sink/DW wall . . . have you considered swapping the sink and cooktop locations? The sink could be under a window looking out to the screen porch (and beyond), and the cooktop could be the focal point on that big wall. It might be nice to have the cooktop further away from your fridge (if it's as busy as mine is! My fridge is in a different location than yours, so that's not an issue for me.) If you did that, you could move the prep sink to the back right corner of the island instead of the back left.

Thanks mama goose. You've given me some things to think about. I like the fridge placement. I am concerned about the depth of the island though. At 42" deep, I'm worried there won't be enough clearance behind the island to have a couch/tv at a comfortable distance. I was trying to leave enough space to walk behind the couch to get to the slider/fridge and just generally to have the couch not too close to the TV. The interior width of the house is 23'. So between back wall of cabinets, island, and aisles (26+48+42+48) I would be looking at the back of the couch being a little over 9 feet to a wall mounted TV. i don't mind a cozy living space but that seems like it might be too tight? We currently sit about 13-15 feet away from the TV (which is 55") and some seating is even farther away. Getting a functional kitchen with a comfortable family area was my biggest struggle when making up this current plan. I'm sorry for the poor quality of the photos/sketches. I'm working from my phone right now as I await delivery of a new laptop It's pretty frustrating. The grip I used is 6" per tiny box, if that helps. Once I get the computer I want to try some digital floor plans. I welcome any feedback. Thanks so much for your plan. I already feel better about the kitchen layout at least

Until you post the plan of the whole floor, here's an idea. I'm thinking a 30" deep counter in front of the low window to give you more room for prep and help avoid things falling off the counter. Here mama goose posted some pictures/links about sink/counters in front of low windows that you can find useful. I'm not sure about the beam, so I tried to avoid a tall cab under it, but if possible, I'd consider pantry on the dining table side, then fridge and a continuous counter on the entry side. The narrow cab on the right of the prep sink can be trash and can be used both during prep and cleanup.
