The island should be placed so as to allow the preferred clearances around it which is 48". 35" is definitely not enough. If that is the cabinet edge to cabinet edge measurement remember you will lose more inches once the countertop is installed. You may also get better advice if you post a picture of the current state with a scale drawing showing dimensions. While you have a good picture of what you're talking about, we haven't seen it. A picture paints a thousand words. :-)

Our island (and pendant lights) are not centered to the stove/hood and I think it looks fine - I’d rather have the “best” clearances for sure!

Sounds like you are already working with less than the minimum recommended clearances to start (averaging you have 40", where minimum is 42"). The aesthetics of this are a lot less important than what you're squeezing with those aisles.

Short answer: symmetry matters not at all so don't worry about it.

Long answer: do whatever you can to get appropriate clearances in your kitchen.

thank you everyone very helpful

(your alignment only "works" from one spot in the house, so alignment is not so important)
