Big big no on the barrier island with insufficient aisles. You're talking a constant obstacle course with bruised hips to even try to work in that. Eliminate all the cabinets on the fridge side if you want an island, and put the sink on the island, and the fridge on the range wall. Otherwise, forget doing an island. You don't have the room needed for people an island in the middle, blocking paths.

You do not even have an overhang so that folks could comfortably sit at the island - adding even a minimal 12" would make the problems so much worse.

Thanks, needed the reality check. Sounds like some reconfiguring is needed. Might be able to fit a 2 person island flipped the other way further from the appliances if I switch some stuff up / remove a cabinet... Back to the drawing board.

Agree with the below. If you are going through this expense, you might as well make a functional layout. Move the sink to the island and the fridge to the range wall. Eliminate all cabs on the right side of the plan entirely.

Also sink with space on only one side would drive me a bit crazy. what are you starting with?

@lharpie the layout I more or less am starting with is what I posted. But in the first version I was planning to remove an existing closet, and swap the position of the oven and fridge. In the below I'd keep the closet and maybe turn it into a pantry. This revised version is pretty much exactly what I'm starting with, but with less cabinets. Not sure where I'd even move the sink if I did. In the mini island would be the microwave and rollout trash. Would remove the 2 stools on the sides when not in use to make more space in the aisles.

That kitchen will work best as a G shape, with a peninsula.
