Five years ago, when I remodeled my kitchen, I invested in a 30-inch DF Wolf range. It more than meets my needs. On the very, very few occasions that warranted it, the range's 4 burners can accommodate all of my largest sauce pans, frying pans, etc. at the same time. The range is very well designed, with lots of space between the 4 burners, and that is why this can be done. The vast majority of the cooking I do (and I do cook a great deal), involves 2 burners operating at a single time, and sometimes a 3rd burner. Plenty of room between the pans when I use this configuration. I wanted the Wolf range and did not want to subtract space from my kitchen counter top/cabinet design (which is on the smaller side) to accommodate a larger range. I've never regretted my decision to go only as large as a 30-inch range. As far as the oven space in a 30-inch range, it more than meets my needs. I use large sheet pans, roasters, etc., with ease and the cavity fits all of my requirements. But....I drive a Subaru, so I'm not into large cars, either! :) Here are a couple of photos of my kitchen so you can see the 30-inch range in a kitchen setting.

I have a 36" sink and 34" window, with trim around it's just over 36". We put uppers on either side. It's definitely a good sized window, however if we didn't need uppers and I could make it larger I think I would probably prefer that because of our view. You seem to have plenty of windows in your mock up so you likely don't need the extra light. You also don't have a lot of uppers so if you took down those in favor of a larger window you'd have far less storage. I think the 33" should be just fine.

Joseph. I had thought of that but not sire of how difficult it would be to find a sink that had the exact cut out but I will let the people actually working with the counter and cabinet let me know if I can do that. haven sells what it calls retrofitted sinks to fit existing cabinetry so perhaps that is also an option. For any soul who wandered into this thread and might worry about their sinks and permits, you probably wouldn’t have any issues. There are more stringent requirements for my sink because I live in a high rise multi family building and theoretically sub standard fixtures would have ramifications for other units in the building unlike a single family home. Of course it’s still insane that a sink which is higher quality can’t be used because it lacks a bureaucratic seal of approval.

Than you all for the comments and feedback so far! Some responses of my own: 1. Agreed, drop the peninsula near the diningroom. That is going away. 2. I know seating on both sides of the peninsula is somewhat limiting, but that's imporant to me because I love being able to have a cup of coffee in the morning and sit and look directly into my beautiful sunroom and watch tv. Having an eat-in kitchen separate from dining room has always been important to be because friends and family always hang there. 3. Agreed on doing some counterspace on the fridge side! 4. Agreed that dishwasher should not be on the same side of sink as the range. Some questions: 1. It seems my kitchen proportion wise can handle the 36" range? The pic with the dining peninsula has the 36" range for scale (first one has 30" range). 2. Do I need a second oven or convection/microwave combo? I currently have a 30" cooktop and double wall ovens (27" I believe) on the fridge wall, but I NEVER use them. I just hate the feeling that I'm "losing" something and I worry about resale value. If I do get a second oven, it would likely have to go on the fridge wall (as seen in one of the pics, and that might mean losing that open counterspace (because the full pantry is on other side of fridge and that is a must). I'm thinking maybe just full 36" range and then a good microwave hidden in the pantry maybe. Other potential option is a convection/micro combo beneath the counterspace, but then it's not super easy to use (should be eye level or close to it).
