Do you truly want the opinion that is going to come back or will we all burst your bubble?

COOLING? ? INCONVENIENT . I'd go so far as to say absurd and a mile from two sinks and those are too close to one another. One used will drip all over as you head to a dw and then the dw door will block a path from range to dw.

No, Not really enough enough clearance anywhere and if you need this much "storage" if implies cooking for a crowd. feeding a crowd, maybe two or three cooks? Strive for 48 inches !

Sink and prep sink too close to one another ! Seemingly with no purpose but to clog a corner with fannies.

Table end of island will seat? How many.

.Massive amount of cabinetry. $$$$$. ....with one major window and a wee window

Two dishwashers......Kosher? Hence the "massive? storage?

More important? We aren't seeing this kitchen in context with the entire remodel, all the "living/family around it.

Show the whole. It's no as you have shown, sorry : )

A prep sink is added to serve the frig when it's too difficult to get to the main sink. You have to relocate it for function. All your lowers where possible can be wide drawer units. The distance is measured from counter overhangs. 42 is tight. You'll need a lighting plan with task and ambient lighting of different intensities on dimmers.

Rare is the U shaped kitchen, where an island isn’t a barrier. Here, it definitely is. You’ve got plenty of prep space between the sink and range/cooktop. An island is unnecessary for prep. Plus, by doing your prep in the U, you won’t be dripping your prep stuff, (liquid and chopped solids), across the floor. If you can do with one dishwasher, flip it to the right of the sink, where it won’t interfer with prepping.

Additionally, the plan shows more than ample storage without the island. Make all lower cabs drawers. Much more convenient than doors with pullouts.

As noted by @JAN MOYER, show the plan as it relates to the rest of the rooms adjacent to the kitchen. Right now, the fridge seems to be in limbo…too far from the sink and prep area.

The thing that stuck out instantly is the prep sink in the island. It's so close to your other sink that it's sort of irrelevant.

"Here's the floor plan,( whole reno ) the kitchen isn't accurate"..............

No,? Still not great, It made a bit more sense than that as proposed /you asked us to critique?!

Go back to the drawing board !!!! You're keeping Kosher. ( two dw ).or its a lazy thing?

What did you have for a footprint before this addition? Was the kitchen something else? It's a whole new Foyer? ............who knows, not us

If I am reading the ‘new’ plan compared to the old plan correctly, then I would not want the fridge opposite the powder room. I would use that wall between dining and family for pantry cabinets and put the fridge on that outer wall

I'm with the others: No. The most solid of Nos.

This kitchen assumes you want to maximize cabinetry-cabinetry-cabinetry! Give me as much counter space as possible! What you've created is a PacMan kitchen -- a kitchen with "too much", and you'll always be walking around that island to get to what you need. Well, no, you won't be walking around it -- not if people are seated in those stools, or if the kids have left the stools pulled out from the island (as they always do). Honestly, it would be hard to draw up a less convenient work space.

Thoughts on improvement -- you're locked into this space, right?

- I love the bay window over the sink -- unique, lovely. Everyone loves this set-up, few people have it. Keep that! But see if you can add a second /smaller window where the pantry is now. Bringing in light from two sides is always a positive, and this'll allow you to see who's at your door.

- Forget the island. Yes, everyone wants an island, but you don't have the right space. Consider instead a peninsula /G-shaped kitchen. Place the entry space towards the dining room. Be sure your barstools won't stick out into the hallway. I'm attaching an image at the end of this post; it's smaller than your space, but I really think this general concept will work so much better than an island.

- Your main question was about aisle space. Note that the whole problem disappears when you ditch the island /go with a peninsula.

- If you do this, you'll be able to ditch the prep sink altogether. The work space will be more consolidated, and the sink (as shown) will be central to all work items.

- This peninsula /G-shaped kitchen pushes all the main work towards where the range is now. So I'd flip the dishwasher to the other side of the sink. This'll keep work toward the range and clean-up on the other side (which is also closer to the kitchen entry /dining room).

- Keep the refrigerator where it is in the original picture (mid-kitchen), and move the pantry to its other side. This'll allow your storage to be just outside your main work area. You'll be able to set grocery bags on the end of the peninsula to "sort" as you put away food. This'll also mean a person can come to the pantry or refrigerator /not enter the main work space /not disturb the cook.

- This concept will bump the range a bit to the left, but that won't matter.

Context of the design and programming decisions would help. Kosher as asked, the room sizes, why the double entry at Powder and Laundry, etc.

In any design, each space contributes to a functional heirarchy. With the refrigerator off to the side leg, that part is also functioning within the Kitchen. If you have the need for a large kitchen, with more food, or more people, or more storage, then that means more seating and/or more dining chairs, more bedrooms. Graphical food for thought:
